Given a cone with a volume of 56.52 in^3 and height 7 in., find the base radius of the cone. use 3.14 for pi. round your answer to the tenths place. a. 2.1 in c. 4.9 in b. 2.8 in d. 4.3 in

B

Step-by-step explanation:

Volume of Cone formula is given by :  

Given V = 56.52 and h = 7, we plug them in and solve for r:

rounding to tenths place, r = 2.8 inches

Answer choice B is right

c.   

Step-by-step explanation:

The volume of cone is given by :-

, where r is radius and h is height of the cone.

Given: Height : 7 in.

Volume :

Then the volume of the cone will be :-

Hence, the radius of the cone =
