The volume of the regtion between two concentric spheres of radii 2 and 5 is

A

28

B

66

C

113

D

490

Text Solution

Verified by Experts

The correct Answer is:
D
Enter the formula for the volume of a sphere `(4//3)pix^(3)` (in the reference list of formulas) into `Y_(1)`. Return to the home screen, and enter `Y_(1)(5)-Y_(1)(2)` to get the correct answer, choice E.
An alternative solutionn is to evaluate `V=(4)/(3)pi(5^(3)-2^(3))=(4)/(3)pi(117)` directly.
