h = 15 cm

Answer 1

Radius = 4 cm

Area = 16π cm²

Volume = 240π cm³

Explanation:

Radius of the given cylinder =
`\frac{\text{diameter of the circular base}}{2}`

=
`(d)/(2)`

=
`(8)/(2)`

= 4 cm

Area of the circular base =
`\pi r^(2)`

Here 'r' = radius of the circular base

Area of the base =
`\pi (4)^(2)`

= 16π cm²

Volume of a cylinder is given by the formula,

V = πr²h

Here 'r' = radius of the circular base

h = height of the cylinder

By substituting the values in the formula,

V = π(4)²(15)

= 240π cm³
