Answer:

A runner wish to jog a circular pathway whose diameter is 100m, and there are 10 flag around the circle n equidistant if, where he started he stopped just in the third flag. What is sector area of the circular pathway?

Step-by-step explanation:

In every post there will be an arc angle of

= 360/10;

= 36 degrees;

since he only utilized 3 posts, means ; 36 × 3= 180 deg;(area measurement);

180/360 = 3/10;

area of the sector = [ 3/10 ]× area of the circle;

area of the = pi(r^2) = pi( 50^2 );

area circle = 2500.pi;

area of the sector = 3(2500)pi/10;

= 750pi m^2...

I Hope it's help to you poh☺️
