Question

What is the volume of a cone with 9cm height and 15cm radius V=1/3pi*r^2*h Use 3.14 for pi

Answer 1

First replace all variables with the respective numbers.

V = (1/3) x 3.14 x 15^2 x 9

according to PEMDAS, work out your exponent next

V = (1/3) x 3.14 x 225 x 9

multiply

V = 1.04667 x 225 x 9

V = 235.5 x 9

V= 2,119.5

ANSWER: the volume is 2,119.5 cm
