Question

Find the radius of the circli whose circumference is 5.28m

Answer 1

hiii!!!

here's ur answer...

circumference of the circle = 5.28m

therefore 2πr = 5.28m

==> 2 × 22/7 × r = 5.28m

==> 44/7 × r = 5.28m

==> r = 5.28/1 × 7/44

==> r = 36.96/44

==> r = 0.84m

in cms = 0.84 × 100 = 84cm

hope this helps..!!

Answer 2

as we know that:
     circumference = 2$\pi$ r
         5.28=2*3.14*r
            r= 5.28/2*3.14
            r=0.8407m
