Question

A cylinder with base radius of 8cm and height of 2cm is melted to form a cone of height 6cm. find the radius of the cone

Answer 1

ANSWER:-

Radius of cylinder =8cm

Height of Cylinder=2cm

Height of Cone=6cm

Now,

the volume of cylinder=volume of Cone

pie r^2×h=1/3pi r^2h

22/7×8×8×2=1/3×22/7×r^2×6

44/7×64=1/3×132/7×r^2

402.28=44/7×r^2

402.28=6.28×r^2

402.28/6.28=r^2

r^2=64

r=8cm

So,Radius of Cone=8cm
