A rectangular sheet of paper measuring 44 cm × 10 cm is folded into a right circular cylinder whose side is 10 cm. What is the approximate volume of the cylinder?

Show answer & explanation

Correct answer: D

Explanation

Length of the rectangle = 44 cm
Width of the rectangle (Height of the cylinder) = 10 cm
Circumference = 2πr
2πr = 44
r=442×227=7r = \frac{44}{2 \times \frac{22}{7}} = 7 cm
Volume of the cylinder = πr²h
=227×72×10=1540= \frac{22}{7} \times 7^2 \times 10 = 1540 cm³
