The height of a cone is 15 cm. If its volume is 1570cm2 , Find the radius of the base (use π=3.14)
Let the radius of the base of cone be r cmGiven height of a cone is h=15 cm
As we know that
Volume of a cone with radius r and height h is 13πr2h
Given volume of the cone is 1570 cm3
⟹13π(r2)(15)=1570
⟹r2=3×15703.14×15=100
⟹r=10 cm
Radius of the base is 10 cm
