Question

the difference between circumference and diameter of circle is 120 m. the area of circle in square metres is

Answer 1

C-d=120m
2πr-2r=120m
2r(π-1)=120
2r(22/7-1)=120
2r(22-7/7)=120
2r(15/7)=120
30/7r=120
r=120×7/30
r=28

Area=πr²
Area=22/7×28²
Area=2464m²

Answer 2

here is your answer

hope this helps you...
