Question

A cone has a height of 11 meters and a radius of 7 meters . What is the volume?

Answer 1

564.512 m³

Explanation:

Formula to find the volume of a cone is :

Volume =
`(1)/(3)` π r² h

Here,

r = radius = 7 m

h = height = 11 m

Let us solve now.

Volume =
`(1)/(3)` π r² h

Volume =
`(1)/(3)` π ×7² × 11

Volume =
`(1)/(3)` π × 49 × 11

Volume =
`(1)/(3)` π × 539

Volume =
`(1)/(3)` × 1693.538

Volume = 564.512 m³

Hope this helps you :-)

Let me know if you have any other questions :-)

Answer 2

V = 564.2 m^3

Explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h where r is the radius and h is the height

V = 1/3 pi (7)^2 (11)

V =539 /3 * pi

Letting pi be approximated by 3.14

V = 564.1533333 m^3

Rounding to the nearest tenth

V = 564.2 m^3
