Question

the inner circumference of a circle is 242 to the track is uniformly 7 metre wide find the area of the track​

Answer 1

Answer:The answer is in hand written form

Step-by-step explanation:

Answer 2

Answer:

1694+49π is the area of the tract.

Step-by-step explanation:

Two concentric circles.

Inner circle:

2πr=242

r=121/π

Outer circle's radius is 121/π +7

Area of the track is the difference between outer and inner circles' areas.

=π(121/π+$7)^{2}$-π(121/π)$π^{2}$

=π[(121/π+$7)^{2}$- (121/π)$π^{2}$]

=π[(121/π+7+121/π)(121/π+7-121/π)]

=π([242/π+7)(7)]

=π(1694/π+49)

=1694+49π
