Question

a 1.75 m path runs along the inside of the boundary of a circular park . if the maximum length between any two points in the park is 84 m , find how much it would cost to pave the path of rs. 20 per meter​

Answer 1

Answer:

2940

Step-by-step explanation:

Answer 2

Answer:

4660

Step-by-step explanation:

Diameter = 84

First lets find the area of the outer circle which is the path

diameter of outer circle = 84 + 1.75 = 85.75

area of circle formula $\pi r^{2}$

$\frac{85.75}{2}$= radius

85.75/2 * 85.75/2 * 22/7

5777.40$m^{2}$ - The inner circle's area

84/2 * 84/2 * 22/7

5544$m^{2}$

5777m^2 - 5544 m^2

233m^2 (approx)

233 * 20 = 4660
