Anna [14]

Answer:

16.49 cubic inches.

Step-by-step explanation:

Given:

A waffle cone has a height of 7 inches and a diameter of 3 inches.

Question asked:

What is the volume of ice cram that can be contained within the cone?

Solution:

First of we will find the radius ;-

Diameter = 3 inches

Radius, r = $\frac{Diameter}{2} =\frac{3}{2} =1.5\ inches$

As we know:

$Volume\ of\ cone=\frac{1}{3} \pi r^{2} h$

$=\frac{1}{3} \times3.14\times1.5\times1.5\times7\\ \\ =\frac{49.455}{3} \\ \\ =16.485$

Thus, volume of ice cream will be 16.49 cubic inches.
