Question

an aluminum can has a diameter of 9cm and a height of 7cm find the volume of the can using 3.14 for tt

Answer 1

The Diameter of the can = 9cm

Radius = Diameter/2

Radius = 9/2 cm

Radius of the can = 9/2 cm

Height of the can = 7cm

The can is in the shape of cylinder

Volume of cylinder with radius r and height h

`\text{Volume of cylinder =}\Pi radius^2* height\text{ }`

Substitute the value and simplify:

`\begin{gathered} \text{Volume of cylinder =}\Pi radius^2* height\text{ } \\ \text{Volume of can =}3.14*(9)/(2)*(9)/(2)*7 \\ \text{Volume of can =}445.095cm^3 \end{gathered}`

The volume of can is 445.095cm cube
