What is the volume of a cylinder with a high of 9 inches in the diameter of 8 inches use 3.14 to approximate pi to calculate the
Natasha_Volkova [10]

Answer:

  452 cubic inches

Step-by-step explanation:

In terms of diameter, the volume of the cylinder is ...

  V = (π/4)d^2h

Filling in the given numbers, we get ...

  V =(3.14/4)(8 in)^2(9 in) = 452.16 in^3

The cylinder volume is about 452 cubic inches.

A cylinder has a volume of 216 pi cubic feet and a hi of 18 ft what is the area of the base? Cylinder v equals BH
VARVARA [1.3K]

Answer:

12π ft² or 37.7 ft²

Step-by-step explanation:

The volume of a cylinder is given by the area of its base multiplied by its height. If total volume is 216 π ft³ and the height is 18 ft, then the area of the base is:

V = Bh\\216\pi = B*18\\B= 12\pi \ ft^2

The base has an area of 12π ft² or 37.7 ft².
