The radius of a cylindrical water tank is 4 ft, and its height is 9 ft. What is the volume of the tank
Use the value 3.14 for it, and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.

169.56 ft.^2

Step-by-step explanation:

alright to find the volume you need to find the area of the base and multiply that by the height.

step one, area of the base.

since the base is a circle, to find the area you need to square the base then multiply by pi.

4 * 4 * pi = 16pi

step 2,, not sure what to call this lol

16pi * 9 = 54pi

step 3, I really shouldn't have given my steps titles

pi = 3.14, so 54pi = 54*3.14

54*3.14 = 169.56

finally, square the unit because volume is 3-d

169.56 ft.^2

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

6mm^3 or .6cm^3
