Find the volume of the cylinder. Round your answer to the nearest tenth.
2 ft
41

157.9 ft^3

Step-by-step explanation:

The formula for the volume of a cylinder is v = πr^2h.

π times the radius which equals 2 and then square the answer which equals a long decimal. Multiply that by the height which is 4. That also equals a long decimal but when rounded to the nearest tenth, you get 157.9 ft^3

The last option.

Step-by-step explanation:

1. By definition the ratio of the perimeter is the same as the scale factor.

2. Keeping this on mind, you can calculate the scale factor as shown below:

3. You can rewrite it as following:

4:3

4. Therefore, the ratio of the perimeter is 4:3
