The diameter of the sphere will be equal to 4.59 feet.

What is a sphere?

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

Given that:-

  • The spheres cost $2 per square foot
  • and Selim can spend $20 per sphere.
  • What is the maximum diameter of the spheres he can purchase?

The area of the sphere will be = 20 / 2 = 10 square feet

The diameter of the sphere will be calculated as:-

Area = 4 π r  

10  =  4 π r

r  =  10 / (  4 π )

r  =   0.79 feet

D = 2r = 2 x 0.79 = 1.59 feet

Therefore the diameter of the sphere will be equal to 4.59 feet.
