Question

**Multiple choice**
The formula for the volume of a cone is V= volume of a cone. Find the radius, to the nearest hundredth, of a cone with a height of 5 in. and a volume of 20 in3.
A. 3.82 in.
B. 1.46 in.
C. 1.95 in.
D. 4.5 in.

Answer 1

r^2=3V/pie h

Answer 2

The volume of a cone is \[V = \Pi r ^{2}h/ 3\]
V= 20; h= 5 and Pi= 22/7
Pi*5* r^2/ 3 = 20
r^2 = 12/Pi
r^2 = 3.81
Therefore r = Square root of 3.81 which approximately is 1.95.
Hence, answer is 1.95 inches.
