Question

the inner circumference of a circular track is 264 metre and the breadth of a track is 7 metre calculate the area of the track​

Answer 1

Answer:

2002 m*2

Step-by-step explanation:

264=2πr then r=42

radius of circle with road = 42+7=49

area of road= (π×49×49)-(π×42×42)

π[(49+42) (49-42)]

= 2002
