Question

Could anyone help with math?? Will up vote, thanks!

Answer 1

Volume of a cone  V = pi * r * r * h / 3
so V = 45, r = 2 therefore 45 = 3.14 * 2 * 2 * h /3  => 45 = 3.14 * 4 * h /3
=> 135 = 3.14 * 4 * h  => 33.75 = 3.14 * h  => 10.75 = h
height = 10.75 cm rounded to 2 decimal places

Answer 2

Answer:

The height of the cone is 10.75 cm.

Step-by-step explanation:

Given the volume of cone = 45 cubic cm

Radius of the cone = 2 cm

Height of the cone = ?

The volume formula of cone is = $\pi r^{2} \frac{h}{3}$

$45= 3.14\times2\times2\times \frac{h}{3}$

=> $45\times3 =12.56h$

=> $135=12.56h$

h = 10.748 ≈ 10.75 cm

So, the height of the cone is 10.75 cm.
