The diameter of the base of a right-circular cylinder is 12 cm and the height of the cylinder is 2.45 times the radius of its base. Find the volume of the cylinder [Use π = $\frac{22}{7}$]
Answer & explanation
Correct answer: option 3
We know that,
Volume of cylinder = πR2H
We have,
The diameter = 12cm
Then, the radius of cylinder = 6 cm
Height = 2.45 times the radius of the cylinder.
According to the question,
Height of the cylinder = 2.45 × 6 = 14.70 cm
Volume of cylinder = πR2H = \(\frac{22}{7}\)× 62 × 14.70= 1663.2 cm2
