Please give the correct answer please...​

Answer 1

Step-by-step explanation:

$\sf\large\underline\purple{Given:-}$

$\displaystyle \sf \bigstar \: \: radius \: of \: a \: first \: cylinder = 7cm \: \: \: \: \: \: \: \\ \\ \displaystyle \sf \bigstar \: \: height \: of \: a \: first \: cylinder = 10cm \: \: \: \:$

$\sf\large\underline\purple{Formula:-}$

$\displaystyle \bigstar\boxed{ \underline{ \boxed{ \bold{volume \: of \: cylinder \: = \pi {r}^{2} h}}}}$

$\sf\large\underline\purple{Answer:-}$

$\displaystyle \bigstar \: \sf \: volume \: of \: cylinder = \pi {r}^{2} h \\ \\ \displaystyle \tt : \implies \: \frac{22}{7} \times 49 \times 10 \\ \\ \displaystyle \tt : \implies \: 1540 {cm}^{3}$

_______________________________________________

$\sf\large\underline\purple{Second:-}$

$\displaystyle \sf \bigstar \: \: \: \: volume = 250 \\ \\ \displaystyle \tt : \implies \: 250 = \frac{22}{7} \times {r}^{2} \times 2 \\ \\ \displaystyle \tt : \implies \frac{250 \times 7}{44} = {r}^{2} \: \: \: \: \: \: \: \: \: \: \: \\ \\ \displaystyle \tt : \implies \: \frac{1750}{44} = {r}^{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \displaystyle \tt : \implies \: \: r \: = \frac{41.2}{6.6} \: \: \: \: \: \: \: \: \: \: \: \: \:$
