Question

Rationalise (2sqrt(3) - 5sqrt(2))/(sqrt(3) + 2sqrt(2)) the denominator

Answer 1

Answer:

⟼Volume of cylinder = 6538 cm3

\longmapsto\sf Height\ of\ cylinder\ =\ 28 cm⟼Height of cylinder = 28cm



\longmapsto\sf Radius\ of\ cylinder\ =\ ??⟼Radius of cylinder = ??

{\huge{\underline{\mathbb{FORMULA\ USED}}}}FORMULA USED

Volume\ of\ cylinder\ =\pi {r}^{2}hVolume of cylinder =πr2h

{\huge{\underline{\mathbb{SOLUTION}}}}SOLUTION

Let the radius be r m

According\ to\ given\ conditionsAccording to given conditions



=>\pi {r}^{2}h=6538=>πr2h=6538

=>{r}^{2}=\frac{6538×7}{22×28}=>r2=22×286538×7

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

Hence, radius= \boxed{8.5}8.5
