If the sphere shown above has a radius of 11 units then what is the approximate volume of the sphere
adell [148]

Answer:

Volume of the sphere=5563.58units^3

Step-by-step explanation:

Volume of the sphere= \frac{4}{3} *\pi *r^3

The sphere has given radius(r)= 11 units

Putting the value of the radius in the formula;

     Volume of the sphere:

                                     = \frac{4}{3} *3.14*11*11*11

                                 =1.33*3.14*11*11*11

                                =4.18*11*11*11

                               =4.18*1331

            Volume   =5563.58units^3

The volume of the sphere with radius of 11 units is 5563.58units^3
