Find the volume and the surface area of a metallic sphere having diameter 8.4cm

answered-by-expert Expert Answer

Given, diameter = 8.4 cm

So, radius = 4.2 cm

Volume =4/3 * pi * r3
Surface area = 4 * pi* r²
Put in the values of r in the formula to get the required volume as 310.46 cm3 and surface area as 221.76 cm2.
