Question

The radius and height of cylinder are in ratio 5 : 7 and volume is 4400 cu.cm
find radius

Answer 1

hope it helps.........

Answer 2

Answer:

☑ Volume of cylinder = π r^2 h

☑ radius and height of a cylinder are in the ratio 5 : 7

r / h = 5 / 7

1 / h = (5 / 7)/ r

1/h = 5/ 7r

h = 7r / 5

Volume of cylinder = π r^2 h

4400 = ( 22 / 7 )[ r^2 ( 7r / 5 )

4400 = (22) r^3 / 5

200 x 5 = r^3

1000 = r^3

r = 10

therefor radius =

$\boxed{\textbf{\large{radius = 10cm}}}$
