Question

Find the height of a cylinder whose volume is 3.08m³ and diameter is 140cm.​

Answer 1

Answer:

$volume = 3.08 \\ diameter = 140 \\ radius = \frac{140}{2} = 70cm \\ volume = \pi \: r^{2} h \\ 3.08 = \frac{22}{7} \times \frac{70}{100} \times \frac{70}{100} \times \frac{70}{100} \times h \\ h = \frac{3.08 \times 7 \times 100 \times 100}{22 \times 70 \times 70} \\ hieght = 2m$

Answer 2

Answer:

The height of a cylinder whose volume is 3.08m³ and diameter is 140cm is 2 m

Step-by-step explanation:

Give diameter of cylinder $= 140 cm = 1.4 m$

Radius of cylinder $= \frac{1.4}{2}=0.7 m$

Volume of cylinder $= \pi r^2h$

Volume of cylinder = 3.08 cubic m

So,

$\frac{22}{7} \times 0.7 \times 0.7 \times h = 3.08$

$22 \times 0.1 \times 0.7 \times h = 3.08$

$h = \frac{3.08}{1.54}$

$h= 2 m$

Hence The height of the cylinder is 2 m​
