Find the volume of a cone with radius 4 inches and height 5 inches. Round your answer to two decimal places

faltersainse [42]

Answer:

Volume of the cone = $83.73$ cubic inches

Step-by-step explanation:

Given:

Radius of the cone= $4 inches$

Height of the cone= $5 inches$

Volume of a cone(V) :

$\pi *r^2*\frac{h}{3}$

Putting the given values in the formula:

Volume of the cone:

$3.14*4*4*\frac{5 }{3}$ : $\pi =\frac{22}{7} =3.14$

$16*3.14*\frac{5}{3}$

$83.73$ cubic inches

So, the volume of the cone up to two decimal places is $83.73$ cubic inches
