The volume of a sphere is 288π cm3 . Find its surface area. |
114π cm2 124π cm2 134π cm2 144π cm2 |
144π cm2 |
We know that, Volume = \(\frac{4}{3}\) πr3 Surface area = 4πr2 We have, The volume of a sphere = 288π cm3 Now, According to the question, 288π = \(\frac{4}{3}\) πr3 = 72 × 3 = r3 = r = 6 Surface area = 4π (6)2 = 4π × 36 = 144π cm2 |
