Question

Find the volume and surface area of a sphere with radius 1 yards. Round your answer to two decimal places.

Answer 1

Volume of the sphere up to two decimal places=
`4.19` cubic yards

Surface area of the sphere up to two decimal places
`=12.56` square yards

Explanation:

Given:

The radius of the sphere= 1 yard

Volume of a Sphere:

`(4)/(3)* \pi *r^3` :
`\pi =(22)/(7) =3.14`

`=(4)/(3)*3.14*1*1*1`

`=4.187` cubic yards

Volume of the sphere up to two decimal places=
`4.19` cubic yards

Surface area of the sphere=
`4*\pi* r^2`

`=4*3.14*1*1`

Surface area of the sphere up to two decimal places
`=12.56` square yards
