${\huge{\underline{\underline{\mathfrak{QUESTION}}}}}$

The volume of a cylinder is 6538 cubic centimetres and its height is 28 cm. find its radius
​

Answer 1

Explanation:

radius = 8.5

csa of cylinder = 1496

explanation:

according to problem

volume of cylinder=6358

πr^2h=6358

22/7xr^2x28=6358

r^2x28=6358x7/22

r^2=72.25

r=8.5

csa of cylinder=2πrh

=2x22/7x8.5x28

=1496

Answer 2

Explanation:

Let the radius be r m

According\ to\ given\ conditionsAccording to given conditions

Volume\ of\ cylinder\=6538{cm}^{3}

= > \pi {r}^{2}h=6538=>πr

2

h=6538

= > {r}^{2}=\frac{6538×7}{22×28}=>r

2

=

22×28

6538×7

= > r=\sqrt{72.25}=>r=

72.25

Hence, radius= \boxed{8.5}

8.5
