Question

3. The circumference of a circle is 264 cm. Find its area.
​

Answer 1

Answer:

we know that

circumference of a circle =264cm

Area of a circle =πr2

Area of a circle =circumference of a circle

πr2=264

22/7*r2=264

r2=264*7/22=84

r=√84=9.16cm

area of a circle =22/7*9.16*9.16=263.70cm2

Answer 2

Answer:

Radius of circle = r 

Circumference = 2πr

2πr = 264

22/7*r = 132

r = 132*7/22

  = 42 cm

Area = πr²

         = 22/7*42*42

         = 5544 cm²
