SA=676pi ft^2

Answer:

Surface area of a sphere= [tex]676\pi ft^2[/tex]

Step-by-step explanation:

the surface area of sphere with radius 13 ft

Surface area of a sphere formula is [tex]4\pi r^2[/tex]

Where 'r' is the radius of the sphere

r= 13 ft

plug in the radius and find surface area

Surface area of a sphere = [tex]4\pi (13)^2[/tex]

= [tex]4\pi *13*13[/tex]

= [tex]676\pi[/tex] square feet
