Question

3. A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi. 12 radius 18 height ​

Answer 1

Answer:

8138.88 cubic unit.

Step-by-step explanation:

Given that,

Radius, r = 12

Height, h = 18

We need to find the volume of the prop. The volume of a cylinder is given by the formula as follows :

$V=\pi r^2 h\\\\V=3.14\times 12^2 \times 18\\\\V=8138.88$

So, the volume of the cylinder is 8138.88 cubic unit.
