Question

Juice is sold in aluminum cans that measure eight inches in height and four inches in diameter. How many cubic inches of juice are contained in a full can?

Answer 1

Aluminum can is in the shape of cylinder whose diameter is 4 inch and height is 8 inches.

\(\therefore\) 2r = 4 inch ⇒ r = 2 inch and h = 8 inch

\(\therefore\) volume of juice in fall com = \(\frac13\pi r^2h\) 

 = \(\frac13\times3.14\times2\times2\times8 \) = 33.49 cubic inches
