Question

THE CIRCUMFERENCE OF TWO CIRCLES ARE
44m AND 88M. FIND THE DIFFERENCE IN
THE AREAS
OF THE CIRCLES.
A. 142 m²
B. 642 m²
C. 462 m²
D. 426 m²​

Answer 1

Answer:

Radius of first circle=2x22/7xradius=44m

44r/7=44

1. r=44x7/44
2. r=7

area of this circle=π*r square

22/7x7square=154

Radius of second circle=2πr=88m

2x22/7x r= 88

44r/7=88

r=14

Area of this circle=π*r square

22/7*14square

=616

difference between their area=462
