Question

A race Track is the form of a ring whose inner circumference is 264 M and Outer circumference is 300 M find the width of the track

Answer 1

Heya!!

Here's ur answer...


_________________________


Inner circumference = 264 m.

$264 = 2\pi \: r \\ r \: = \frac{264 \times 7}{2 \times 22} \\ \\ r = 42 \: m \:$


Outer circumference = 300 m.

$2\pi \: r1 = 300 \\ r1 = \frac{300 \times 7}{2 \times 22} \\ \\ r1 = 47.7m$



Width = r1 - r
= 47.7 - 42
= 5.7 m.
