Two identical circular plates, each at their maximum size, are cut from a circular sheet of paper with a circumference of 352 cm. The circumference of each circular plate is
Show answer & explanation
Correct answer: A
Explanation
Given:
Circumference of the larger circle = 352 cm
By the formula:
Circumference = 2πr
2πr = 352
2 × (22/7) × r = 352
44r/7 = 352
r = 56 cm
Radius of the larger circle = 56 cm
Two equal maximum circles are cut out ⇒ Radius of each = 56/2 = 28 cm
Now the circumference of each smaller circle = 2πr
= 2 × (22/7) × 28
= 176 cm
