Answer: Choice A) 85 cubic inches

==========================================

Step-by-step explanation:

The sand is in the form of a cylinder with radius r = 3 (half of the diameter d = 6) and height h = 3.

V = volume of cylinder with radius r and height h

V = pi*r^2*h

V = 3.14*3^2*3

V = 84.78 cubic inches

To the nearest whole cubic inch, the volume of the sand is approximately 85 cubic inches.

Note how we never used the height of 12 inches, as that is just extra unneeded info.

Answer:

24 pi

Step-by-step explanation:

find area of base which is a circle

A = pi x r x r

here r is 3 inches

3.14x 3 x 3 = 8 pi

multiply this by the height of the sand which is 3

8 pi x 3 = 24 pi
