Answer 2

Question:

The volume of a sphere is 523.3 cubic feet. To the nearest foot, what is the radius of the sphere? Use 3.14 for π.

    Step-by-step explanation:

The volume of a sphere is 523.3

we, need to find the radius of sphere= ?

instead of $\pi$ we can use = 3.14

then volume of sphere is V= 4/3$\pi$r³

now volume of sphere = radius of sphere

V= 4/3$\pi$r³= ?

4/3×3.14×r³=523.3                              

4×3.14×r³=523.3×3                

4×3.14×r³=1569.9‬            

12.56×r³=1569.9                

r³=1569.9/12.56    

r³=124.99203821656

r=∛124.99203821656

r=4.99989384

      Verification:

4/3$\pi$r³=volume of a sphere

4/3×3.14×4.99989384×4.99989384×4.99989384

volume of sphere= 523.2999998010809 (approx)

hence it is proved , radius=4.99989384  

radius value also correct

Hope it will helpful to you :)
