Question

Hasmeet walks once round a circle with a diameter of 80m. There are eight points equally spaced on the circumference of the circle. Find the distance Hasmeet walks between one point and the next point.

Answer 1

Answer with explanation:

 Diameter of circle =80 m

Radius of circle

                   $=\frac{\text{Diameter}}{2}\\\\=\frac{80}{2}\\\\=40 m$

Total length of circle having diameter 80 m= Circumference of this circle

      = 2 π × (Radius of circle)

      = 2 × 3.14 × 40

     = 80 × 3.14

     =251.2 m

It is also given that, there are eight points equally spaced on the circumference of the circle.  

Distance that Hasmeet walks between one point and the next point

        $=\frac{251.2}{8}\\\\=31.4 m$

Answer 2

Circumference = πD
Circumference = π(8)m

There are 8 points, 
Distance between two points = 8π ÷ 8
Distance between two points  = π or 3.14m
