Find the volume of the cone.

8_murik_8 [283]

Answer:

$V=471\ \text{units}^3$

Step-by-step explanation:

Given that,

Radius of the cone, r = 5 units

Height of the cone, h = 6 units

We need to find the volume of the cone. The formula for the volume of the cone is given by :

$V=\pi r^2 h$

Substitute all the values,

$V=3.14\times 5^2\times 6\\\\V=471\ \text{units}^3$

So, the volume of the cone is $471\ \text{units}^3$ .

3h = $93.75

Divide by 3.

h = $31.25

The mechanic charges $31.25 per hour for labor.

Hope that helps.
