Question

Q.15. If the vertical height
of a cone is 8 cm and the
area of its base is 1.56
cm 2 then its volume is?​

Answer 1

Answer:

Given the vertical height of cone is 8 m and area of base is 156 sq m

Let radius of cone is r m 

Then base area =πr2=156⇒r2=156πm

And the volume of cone=31πr2h=31×156π×8=416m3
