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

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

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
