What is the volume of a cylinder, in cubic feet, with a height of 8 feet and a base diameter of 18 feet? Round to the nearest tenths place

2034.7 ft³

Step-by-step explanation:

To calculate the volume of a cylinder, use the formula V = bh.

The base of a cylinder is a circle, therefore you must solve for the area of a circle using the formula A = πr²

Since the diameter is given as 18, half of that is the radius, or 9. Plug this into the formula for the area of the base:

A = 9²π

A = 81π ≈ 254.34

That is the area of the base. Plug that into the equation for the volume of a cylinder:

V = (254.34) · 8

V = 2034.72 ≅ 2034.7 ft³ (Rounded to tenths)

its 4 because 2 times 2 is 4, if you double the number two you get four
