The net of a right circular cylinder is shown. Where the radius of each circle is labled 5 meters and the height of the rectangle is labled 8 meters. What is the surface area of the cylinder?
A: 220 m2
B: 283 m2
C: 408 m2
D: 628 m2

Answers

Answer:

The surface area of the cylinder is equal to: C. 440 m².

How to calculate surface area of a cylinder?

Mathematically, the surface area (SA) of a cylinder can be calculated by using this formula:

SA = 2πrh + 2πr²

Where:

h represents the height.

represents the radius.

By substituting the given parameters into the surface area of a cylinder formula, we have;

Surface area (SA) of cylinder = (2 × 3.14 × 5 × 9) + 2 × 3.14 × 5²

Surface area (SA) of cylinder = 282.6 + 157

Surface area (SA) of cylinder = 439.6‬ ≈ 440 square meters.

A county has constructed a conical building to store sand. The cone has a height of 195 ft and a diameter of 307 ft. Find the volume of this building to the nearest hundredth. Use 3.14 for π.

Answers

Answer:

Volume of cone=4809055.225ft^3

Step-by-step explanation:

Height=195ft

Diameter=307ft

Radius=Diameter/2

=153.5ft

Volume of cone=π r^2 h/3

=3.14 (153.5ft)^2 (195ft/3)

=3.14 (23562.25ft^2) (195ft/3)

=3.14 (4594638.75ft^3/3)

=3.14 (1531546.25ft^3)

=4809055.225ft^3

Answers

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

PLEASE HELP!!!
2/7(9 + 2/3m + 7n)
Find the product.

Answers

Answer:

6/7 + 4/21m + 2n

Step-by-step explanation:

The expression 2/7 * (9 + 2/3m + 7n) can be simplified as follows:

Step 1: Simplify the expression inside the parentheses:

9 + 2/3m + 7n = 9 + (2/3)m + 7n

Step 2: Multiply the simplified expression inside the parentheses by 2/7:

2/7 * (9 + (2/3)m + 7n) = 2/7 * (9 + (2/3)m + 7n)

Step 3: Distribute the 2/7 to each term inside the parentheses:

2/7 * 9 + 2/7 * (2/3)m + 2/7 * 7n

Step 4: Simplify the expression by multiplying each term by 2/7:

(2/7) * 9 = 6/7

(2/7) * (2/3)m = 4/21m

(2/7) * 7n = 2n

Step 5: Combine like terms:

6/7 + 4/21m + 2n = 6/7 + 4/21m + 2n

The final result of the product is 6/7 + 4/21m + 2n.

We can use distributive property.

The question is 2/7(9+2/3m +7n)

Step 1: 2/7(9) + 2/7(2/3m) + 2/7(7n)

Step 2: 6/7 + 4/21m + 2n

Answer: 6/7 + 4/21m + 2n

To find the interest earned by Account A, we can use the formula:

Interest = Principal x Rate x Time

Plugging in the given values, we get:

Interest = $1,500 x 0.04 x 3 = $180

So Account A earns $180 in interest over three years.

Similarly, we can find the interest earned by Account B using the same formula:

Interest = Principal x Rate x Time

Plugging in the given values, we get:

Interest = $1,500 x 0.06 x (21/12) = $157.50

So Account B earns $157.50 in interest over 21 months.

To compare the interest earned by the two accounts, we can see that Account A earns more interest than Account B, even though the interest rate is lower. This is because the time period is longer for Account A, giving the interest more time to accrue.

Example 1: Two principal amounts and two simple interest rates that would earn equal amounts of interest in one year are:

Principal 1 = $1,000
Rate 1 = 5%
Interest 1 = $50

Principal 2 = $2,000
Rate 2 = 2.5%
Interest 2 = $50

Example 2: Two principal amounts and two periods of time for which the simple interest earned at 2.59% would be equal are:

Principal 1 = $500
Time 1 = 4 years
Interest 1 = $51.80

Principal 2 = $1,000
Time 2 = 2 years
Interest 2 = $51.80

1. The longest pencil is 8 inches and the shortest pencil is 2 inches. Therefore, the difference between the length of the longest pencil and the shortest pencil is 8 - 2 = 6 inches.

2. Pencils measuring less than 5 inches: 3 + 2 + 3 = 8 inches in total.

3. False. To determine if more than half of the pencils are 6 inches or shorter, we need to find the total number of pencils and calculate how many of them are 6 inches or shorter.

Total number of pencils = 4 + 3 + 2 + 3 + 7 + 8 = 27

Number of pencils that are 6 inches or shorter = 4 + 3 + 2 + 3 = 12

To find out if more than half of the pencils are 6 inches or shorter, we need to divide the number of pencils that are 6 inches or shorter by the total number of pencils and multiply by 100%:

12/27 x 100% = 44.44%

Since 44.44% is less than 50%, the statement is false.

4. There are three pencils that measure more than 5.5 inches but less than 7.5 inches: 6, 6, and 7. Therefore, the answer is 3 pencils.

What is the value of x and y?

Answers

Answer:

x = 5/4

y = 15/16

Step-by-step explanation:

y = 3/4x

5/2 x + 2y = 5

Substitute the first equation into the second equation

5/2x + 2(3/4x) = 5

5/2x + 3/2x = 5

Combine like terms

8/2x = 5

4x = 5

Divide by 4

4x/4 = 5/4

x = 5/4

Now find y

y = 3/4 x = 3/4 ( 5/4) = 15/16

X=5/4
Y=15/16
