the inner circumference of a circular track is 242 me the track is uniformly 7 wide find the area of the track​

Answer 1

Answer:

$\huge\blue{\boxed{\red{\mathfrak{\overbrace{\underbrace{\fcolorbox{red}{aqua}{\underline{\red{✯answer✯}}}}}}}}}$

Circumference of the inner circle=2πr=24π =>r=12m

Radius of the outer circle =14m

Therefore, circumference of the outer circle =2π(14)

=2×22

=88m

(Assuming π= 7).

OR

Circumference of the inner circle=2πr=24π

=>r=12m

Radius of the outer circle =14m

Therefore, circumference of the outer circle

=2π(14)

=2×22

=88m

Answer 2

Answer

inner radius=242×7/44=27.5cm

width of track 7cm

external radius=34.4cm

area of track=22/7 (34.5)^2-(27.5)^2

=22/7×434

=22×62

=1364cm^2
