Question

Height 20cm,volume 12320cm3, find radius

Answer 1

Answer:

Step-by-step explanation:

Volume of cylinder = πr^2h

12320 cm^3 = 22/7*r*r *20

r^2 = 78400

r= 280 cm

Answer 2

Answer:

Step-by-step explanation:

radius = ?

Height = 20

The volume of cylinder is πr^2h = 12320

π × r × 20 = 12320

π × r = 12320/20

22/7 × r = 616

r = 616 × 7/22

r = 196 cm

So the radius of the cylinder is 196 cm
