Question

Find the volume of the specified cone. Use 3.14, and round your answer to the nearest whole number.

Diameter = 5 cm, Height = 9 cm

Answer 1

Answer: 59 cubic cm.

Explanation:

The volume of cone is given by :-

`V=(1)/(3)\pi r^2 h`, where r is radius and h is height of the cone.

Given: Diameter : 5 cm

Then Radius =
`(5)/(2)=2.5\ cm`

Height : 9 cm

Then , the volume of the cone will be :-

`V=(1)/(3)(3.14) (2.5)^2 (9)=58.875\approx59\text{ cm}^3`

Hence, the volume of the cone = 59 cubic cm.

Answer 2

The formula for the volume of a cone is V=(1/3)πr^2h.
To find r (radius) divide the diameter by 2, giving you 2.5 cm.
Plug in the numbers now !
V=(1/3)(3.14)(2.5^2)(9)
V=(1/3)(3.14)(6.25)(9)
V=(1/3)(176.625)
V=58.875
Therefore, the volume of the cone is about 59cm^3 :)
