What Are The Circumference Of Each Circular Plate
Answer: (1). 176 cm
The circumference of a large circular paper sheet is 352 cm.
and two maximum sized circular plates are cut from it. therefore, the radius of a large circle is the diameter of small circles. Let R is the radius of large circle & the small circle is r.
Circumference of large circle = 2πR
352 = 2πR
352×7/44 = R
56 = R.
The radius of the large circle is a diameter of the small circle.
Therefore, R/2 = r
56/2 = r
28 = r
Then, circumference of small circle = 2πr
= 2x (22/7) X28
So, the circumference of small circles is 176cm each.
