Question

Oscar the Grouch has a cylindrical trash can with a diameter of 20 cm and a height of 46 cm. What is the approximate volume of the can?

A. 2,908 cubic cm

B.4,600 cubic cm

C.926 cubic cm

D.14,444 cubic cm

Answer 1

The area of the opening is PI x r^2

Area = 3.14 x 10^2 = 314 square cm

Now multiply by the height:

Volume = 314 x 48 = 14,444 cubic cm.
