Question

how to find radius of circle if circumference is 176Cm answer with photo

Answer 1

Heyaa,

As we know that ..

Circumference of circle= 2πr(r= radius).

so, 176= 2πr

πr= 176/2= 88
r= 88/π.

r= 28( approx).

Answer 2

circumference of circle =2 pie radius
176cm =2 pie r
176cm=2×22/7×r
176cm/2=22/7×r
88cm=22/7×r
(88×7)/22=r
28cm=radius
