Question

Find the volume of the figure below? A) 576 cubic cm. B) 900 cubic cm. C) 1440 cubic cm. D) 785 cubic cm.

Answer 1

`C`

Explanation:

So,total volume = volume of cylinder + volume of cone = `pi r^2 h + 1/3 pi r^2 (25-h)`

Given, `r=5 cm,h=15 cm`

so,the volume is `(pi (5)^2 *15 +1/3 pi (5)^2 *10 ) cm^3=25pi(15+10/3) cm^3=1439.9 cm^3`
