The volume of a cone with a radius of 7 cm is [tex]147\pi[/tex] cubic centimeters. Which expression can be used to find [tex]h[/tex], the height of the cone?

A. [tex]147\pi = \frac{1}{3} (7) (h)^2[/tex]
B. [tex]147\pi = \frac{1}{3}\pi (7^2) (h)[/tex]
C. [tex]147\pi = \frac{1}{3}\pi h[/tex]
D. [tex]147\pi = \frac{1}{3}\pi (7) (h)[/tex]

Answer :

volume(V)=147cm^3

also,

v=1/3×3.14×7^2×h

or, 147×3=3.14×49×h

or, (441)/(3.14×49)=h

or, h=2.87cm

Answer:its B
