Question

The water in cylinder A of radius 24 cm and height of 15cm is poured into another cylinder B of radius 36 cm. Find the height of water in cylinder B

Answer 1

Answer:

6.67 cm

Step-by-step explanation:

Volume of the water remain same!

$\pi r_{1} ^{2}  h_{1} =  \pi r_{2} ^{2}  h_{2}$

$r_{1} ^{2}  h_{1} =  r_{2} ^{2}  h_{2}$

24×24×15 =36×36×$h_{2}$

8640 = 1296 × $h_{2}$

$h_{2}$ = $\frac{8640}{1296}$

$h_{2}$ = 6.67 cm
