Question

from a circular sheet of radius 6 centimetre a circle of radius 4 cm is removed find the area of the remaining sheet

Answer 1

==================================
⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐
==================================

We know already that to calculate the area of any circle we use the formula πr² (where, π is equal to 22/7 and r is the radius of that circle).

Therefore,

Area of the circular sheet

= 22/7 × (6)² cm²

Area of the circle cutted out

= 22/7 × (4)² cm²


So, The area of the remaining sheet

= Area of the circular sheet - Area of the circle cutted out

= {22/7 (36-16)} cm²

= {22/7 × (20)} cm²

= 440/7 cm²

= 62.86 cm² (Approx.)
