Question

the volume of a right circular cylinder is 392cm and it height is 8cm find the radius​

Answer 1

Answer:

3.98 nearly equal to 4

Step-by-step explanation:

Volume of right circular cylinder(V)=$\pi$r^2h

where given height(h)=8cm;

V=392cm^3

392=$\pi$r^2(8)

r^2=7*7*7/22

Therefore,r=3.98
