Question

The circumferences of two circles are 264 meters and 352 meters. Find the difference between the areas of the larger and the smaller circles ?

Answer 1

hlo

taking circumfrence = 264m
circumfrence = 2πr
2 × 22/7 × r = 264
r = 264× 7/ 22 × 2
r = 1848 / 44
r = 42

area if circle = .πr^2
22/7 × ( 42)^2
22/7 × 1764
22 × 252 = 5544 m^2



taking circumfrence = 352
2πr =352
2 × 22/7 × r = 352
r = 352 × 7 /22 × 2
r = 56

area = πr^2
22/7 × ( 56)^2
22/7 × 3136
22 × 448
9856m^2

difference = 9856 - 5544
