Question

If the surface area of a sphere is 616 cm?, then find its radius.​

Answer 1

Answer:

here's ur answer......

Answer 2

Answer:

Surface area = 616 cm^2 , Radius =?

Step-by-step explanation:

Surface area of a sphere = 4πr^2

So,                               616 = 4*(22/7)*r^2

                                    r^2 = 616*7/4*22

                                    r^2 = 154*7/22

                                    r^2 = 7*7

                                        r = √49

therefore,                         r = 7 cm
