Solution:
Given height of a cone, h = 15 cm
Volume of the cone = 1570 cm3
(1/3)r2h = 1570
(1/3)3.14 ×r2×15 = 1570
5 ×3.14×r2 = 1570
r2 = 1570/5×3.14 = 314/3.14 = 100
r = 10
Hence the radius of the cone is 10 cm.
The height of a cone is 15 cm. If its volume is 1570 cm2 , find the radius of the base. (Use π = 3.14)
