The rectangular paper sheet of length 88 cm and width 11 cm is folded along its length to made a cylinder. Find the radius of the base of the cylinder.

14 cm

The length of the rectangle becomes circular base of the cylinder, such that circumference of the base of the cylinder will be = 88 cm.

⇒ Circumfrence = 2 \(\pi \) r = 88

⇒ 2 \(\frac{22}{7}\) r = 88

⇒ r = \(\frac{7 × 88}{22 × 2}\) = 14 cm.
