What is the value of x, if the volume of the cone is 12 pi m^3?
4 m
5 m
6 m
10 m

4 m

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

12 pi  = 1/3 pi  (3)^2 x

12 pi = 1/3 pi 9 x

12 pi = 3pi x

Divide each side by 3 pi

12 pi / 3pi = 3pix/ 3pi

4 =x

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
