Question

Two cylindrical jars contain the same amount of milk if their diameters are in a ratio of 3:4find the rato of their heights

Answer 1

Hey mate...☺☺

here is ur ans...✌✌

Let the ratios be x. 3x and 4x

Curved surface area of cylinder =
$2\pi \: rh$

Radius1 = 3x/2
Radius2 = 4x/2 = 2x


CSA 1 =
$= > 2 \times \frac{22}{7} \times \frac{3x}{2} \times h \\ \\ = > \frac{66x}{7} \times h$


Now CSA 2 =
$= > 2 \times \frac{22}{7} \times 2x \times h \\ \\ = > \frac{88x}{7} \times h$

So the ratios of their heights = 66x/7 ÷ 88x/7
=> 66x/7 × 7/88x
=> 3/4
=> 3:4

Hope it helps u...✌✌

Thanks...❤❤
