Question

A building is made of a cone and a right circular cylinder. The height of the cylinder is 210 cm and the height of the cone is 21 cm. The
radius of the base of the cylinder and the base of the cone is 14 cm. Find the capacity of the building.

​

Answer 1

Answer:

133672 cm^3

Step-by-step explanation:

Volume / Capacity of building -

Volume of cone + volume of cylinder

Volume of cone =

$1 \3 \: \: \pi r ^{2} h$

= 1/3 × 22/7 × 14 × 14 × 21

= 4312 cm^3

Volume of cylinder =

$\pi \: r ^{2} h$

= 22/7 × 14 ×14 × 210

= 129360 cm^3

Volume of building = 4312 + 129360

= 133672 cm^3
