Question

the value of a cylinder is 448x cm cube and height is 7 cm find its radius

Answer 1

Volume = πr^2 h
Curved surface area= 2πrh
Total surface area= 2πrh+2πr^2

πr^2*7=448 π
r^2=64
r=8

Answer 2

Hey

Here is your answer

Volume of cylinder = 448pi
pi × r^2 × h = 448 pi
r^2 × 7 =448
r^2 = 64
r = 8 cm
