Answer: D
Explanation: to find the volume of the cone you would have to use the formula:
1/3* pi* r^2* h
If the dimensions are to be plugged in the formula would then be
1/3* 3.14* 4^2 * 12
Therefor the volume of the cone is 201.06 in^3
Moving on to the cylinder, the formula used would be
V=Bh
To find B the formula used would be
B= pi* r^2
Plugged in the formula would turn unto
B= 3.14* 3^2
The volume of the cylinder is 226.19
When subtracted, the area if the cylinder is about 25 cubic inches less than the cone, so the answer is D.
