Question

find the height of the cylinder whose volume is 1.5cu m and diameter is 140 cm?​

Answer 1

Step-by-step explanation:

Let h be the height of cylinder whose radius,

r=

2

140

cm=70cm=

100

70

m=0.7m

and volume =1.54m

3

.

Now, volume =1.54cm

3

⇒πr

2

h=1.54

⇒

7

22

×0.7×0.7×h=1.54

⇒h=

22×0.7×0.7

1.54×7

=1

Hence, the height of the cylinder is 1m.
