Question

radius and height of a cylinder are in ratio 5 ratio 7 and Its volume is 550cm.Find it's radius​

Answer 1

Answer:

Step-by-step explanation:

If radius = 5x

Height = 7x

πr^h = 550

22/7×25x^2×7x = 550

x = 1

Radius = 5×1 = 5cm

Answer 2

Answer:

5/7=r/h

5h=7r

h=7r/5

volume=πr2h=550

22/7(r)2(7r/5)=550

r3=550×5/22

r3=25×5

cube root both side

r=5
