A party hat has a diameter of 10 cm and 15 cm tall what is the volume of the hat

V = 125 pi cm^3

V = 392.6990817 cm^3

Step-by-step explanation:

Volume of a cone = 1/3 pi r^2 h

The diameter is two times the radius

d = 2r

10 = 2r

10/2 = 2r/2

5 = r

V = 1/3 * pi * (5) ^2 * 15

= 1/3 * pi * 25 * 15

=125 * pi

Approximate pi as 3.14

V = 392.6990817 cm^3

V = 125 pi cm^3

V = 392.6990817 cm^3
