A metal sphere of radius 10.5cm is melted and casted in to 18 identical small solid right circular cones. The height of a cone is 7cm. In this process a volume of 94.59 cm³ of metal is wasted. Taking the value of n as 3.14. 1. ii. iii. Calculate the volume of the metal sphere. Find the volume of a casted cone and show that the base of radius r of the cone is given by, 792 r² = 21.98 Using the logarithmic table find the value of r² and accordingly find the value of r.
