Question

What is the surface area of sphere with radius 13 ft?

676π ft2
2704π ft2
208π ft2
52π ft2

Answer 1

SA=4pir^2
SA=4pi13^2
SA=4pi169
SA=676pi ft^2

Answer 2

Surface area of a sphere=
`676\pi ft^2`

Explanation:

the surface area of sphere with radius 13 ft

Surface area of a sphere formula is
`4\pi r^2`

Where 'r' is the radius of the sphere

r= 13 ft

plug in the radius and find surface area

Surface area of a sphere =
`4\pi (13)^2`

=
`4\pi *13*13`

=
`676\pi` square feet
