The volume of a cone with a height of 6 cm is 8 pi cubic centimeters. Which expression can be used to find r, the radius of the base of the cone? 6 = one-third pi (r squared) (8 pi) 8 pi = one-third pi (r) (6 squared) 6 = one-third (pi r)(8 pi) 8 pi = one-third pi (r squared) (6)

Answer:

last option is correct

Explanation:

Mathematically, we can write the volume of a cone as;

V = 1/3 * pi * r^2 * h

From the question, V is 8 pi cm^3 while h is 6cm

Thus, substituting these values into the equation, we have;

8pi = 1/3 * pi * r^2 * 6

The last option is the correct answer that tallies with the above
