Question

What is the volume of a come that has a height of 40 millimeters and a diameter of 25 millimeters? Use 3.14 for pi.

Answer 1

6541.7 mm³ (nearest tenth)

Explanation:

`\boxed{volume \: of \: cone = (1)/(3)\pi {r}^(2)h }`

Given that the height is 40mm, h= 40mm.

Diameter= 2(radius)

Radius of cone

= 25 ÷2

= 12.5mm

Volume of cone

`= (1)/(3) (3.14)(12.5)^(2) (40)`

= 6541.7 mm³ (nearest tenth)
