Given - r= 3.5 cm
Therefore surface area of sphere = 4πr^2 = 4 x 3.14 x 3.5 x 3.5 = 153.94cm²
Volume of sphere = 4/3πr^3 = 4/3 x 3.14 x 3.5 x 3.5 x.3.5 = 179.59cm³
Therefore surface area of sphere = 4πr^2 = 4 x 3.14 x 3.5 x 3.5 = 153.94cm²
Volume of sphere = 4/3πr^3 = 4/3 x 3.14 x 3.5 x 3.5 x.3.5 = 179.59cm³
