What is the height of the cone below? V = 45 in^3 B = 5in^2

Lapatulllka [165]

Answer:

The height of the cone is h = 27

Step-by-step explanation:

Formula:-

Step 1:-

The volume of the cone is $V=\frac{1}{3} (base)(height)$

Given volume is V= 45 in^ 3

Given base of the cone is B= 5 in^2

Step 2:-

by using formula, we get solution

$45 = \frac{1}{3} (5)(h)$

cross multiplication, we get

$\frac{45 x 3}{5} =h$

now simplification, the height of the cone is h = 27
