Question

The radius of the base and height of a right circular cylinder cone are doubled. The volume of cone isr

Answer 1

Answer:

Volume of cone(V) = 1/3Πr^2h

R'= 2r

H'=2h

V'= 1/3Π R'^2 H'M

= 1/3 Π (2r)^2 2h

= 1/3 Π 4r^2 2h

= 8/3 Π r^2 h

= 8 V

Hence the new volume is 8 times the old volume
