✔ 最佳答案
π(22/2)^2 x 7= 22/7 x 11^2 x 7
= 22/7 x 7 x 121
= 22 x 121
= 2662 cubic centimeters

= Ï (11)(11) (7)
= 2660.93 cubic cm

volume of a cylinder is v=pi times the radius squared times the height.
your height is 7, and remember that radius is half of the diameter, so your radius is 11.
radius squared would then be 121
the volume is then 121*pi*7
2660 cm^3

It is just the area of the end of the cylinder times the height of the cylinder. Since the diameter is 22, the radius is 11 and the area is pi time the radius squared. I will leave the little bit of math up to you.

V = (area of base)h
base is a circle
V = pi(r)^2(h) = pi(11)^2(7)
base is a circle
V = pi(r)^2(h) = pi(11)^2(7)
