A right circular cone has a volume of 247 cubic

inches. If the height of the cone is 2 inches, what

is the radius, in inches, of the base of the cone?

A) 2/3

B) 6

C) 12

D) 36

Answer:10.9 inch

Step-by-step explanation:

Volume=247

Height (h) = 2

π=3.14

Radius=r

Volume = (π x r^2 x h) ➗ 3

247 = (3.14 x r^2 x 2) ➗ 3

Cross multiplying we get

247x3 = (6.28r^2)

741=6.28r^2

Divide both sides by 6.28

741/6.28=6.28r^2/6.28

r^2=117.994

r=√ (117.994)

r=10.9
