Question

Does anyone know the answer.

Answer 1

The volume is approx. 170 cubic inches.

Explanation:

The total volume is the sum of the volume of the cylinder and half the volume of a sphere with the given diameter.

Cylinder:

(volume) = 2 * (disc area) * (height)

`V_C=\pi r^2 h = \pi (d^2)/(4)h=3.14\cdot 6.25\cdot 7=137.4 \,\,in.^3`

Hemisphere:

`V_H=(1)/(2)\cdot(4)/(3)\pi r^3=(2)/(3)\cdot 3.14\cdot 2.5^3=32.7\,\,in^3\\`

Total:

137.4+32.7 = approx. 170 cubic inches
