Question

A 50- centimeter piece of wire in bent into a circle. What is the area of this circle

Answer 1

The answer would be: 199.08 cm^2

Answer 2

50cm would be the circumference.

Formule for circumference is:

C=2(pi)r

Solve for radius:

50=2(pi)r

r=50/2(pi)

r=7.96

Use this to solve for area

A=(pi)r^2

A=(pi)(7.96)^2

A=199cm
