Answer:
[tex]A=7569\pi \ ft^2[/tex]
Step-by-step explanation:
The diameter of a sphere is 87 feet.
We need to find its surface area. The formula for surface area is given by :
[tex]A=4\pi r^2[/tex]
Where
r is the radius of the sphere
[tex]A=4\pi \times (\dfrac{87}{2})^2\\\\=7569\pi \ ft^2[/tex]
So, the surface area of the sphere is equal to [tex]7569\pi \ ft^2[/tex].
