From a circular sheet of circumference 264 cm, two equal maximum-sized circular plates are cut off. What will be the circumference of each plate? (Use π = )
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 132 cm.
The circumference of the circle = 2πr
here, r = radius of the circle
Now,
⇒ 264 = 2 × 22/7 × r
⇒ r = (264 × 7)/44
⇒ r = 42 cm
Since two equal maximum-sized circular plates are cut from the original circular sheet
Radius of the plate = 42/2 = 21 cm
So,
CIrcumference of the plate = 2πr = 2 × 22/7 × 21 = 44 × 3 = 132 cm
Thus, The circumference of each plate is 132 cm
