Question

10. A racetrack is in the form of a ring whose inner circumference is 352 m
and outer circumference is 396 m. Find the width and the area of
the track

?
can somebody find the area of thish questions??? ​

Answer 1

Answer:

let the inner radius=r

outter radius=R

2πr=352m

r=(352/2×22)×7

r=56m

and 2πR=396m

R=(396/2×22)×7

R=63m

width of the tract=R-r

=63-56

=7 m

again,

Area of the tract(A)=π(R+r)(R-r)

=π(63+56)(63-56)

=π(119)(7)

=22/7×119×7

=2618 m^2
