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.
Answer & explanation
Correct answer: option 1
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.
