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☺️
