Volume of cylinder = 22/7 * r * r * h
r = 5x
h = 7x
= 22/ 7 * 5x * 5x * 7x = 550
22 * 25x * x * x = 550
25x3 = 550 / 22
25x3 = 25
x3 = 25 / 25
x3 = 1
x = 1 cm
Radius = 5x = 5 * 1 = 5 cm
r = 5x
h = 7x
= 22/ 7 * 5x * 5x * 7x = 550
22 * 25x * x * x = 550
25x3 = 550 / 22
25x3 = 25
x3 = 25 / 25
x3 = 1
x = 1 cm
Radius = 5x = 5 * 1 = 5 cm
