Question

In a park or radius 700 m there is a circular fountain of radius 5 m . Calculate the total walking area available to pedestrians visiting the park.

Answer 1

Answer:

1538521.5 m$^2$

Step-by-step explanation:

Bigger circle (whole park) radius = 700 m

Smaller circle (fountain) radius = 5 m

Whole park area = $\pi$ x 700$^2$ = 1538600 m$^2$

Smaller circle area = $\pi$ x 5$^2$ = 78.5 m$^2$

Walking area = 1538600 - 78.5 = 1538521.5 m$^2$
