circumference of circle 2πr=176
2×22/7×r=176
r=176×7/22×2
=4×7 =28
2×22/7×r=176
r=176×7/22×2
=4×7 =28

Circumference of circle=π*diameter
176 cm =π*diameter
176=22/7*diameter
Diameter=176/(22/7)
Diameter=56
Radius =diameter/2
=56/2
=28cm
Let's check our answer
LHS RHS
Circumference=2πr
176=2*22/7*28
176=176
LHS=RHS
Therefore our answer is correct :-)
