Answer:

508.85 cm^2

Step-by-step explanation:

Given data

Circumference=  80.01 centimeters

We know that the expression for circumference is

C= 2πr

Substitute to find r

80.01 =2*3.142*r

80.01= 6.284*r

r=  80.01/6.284

r= 12.73 cm

The radius is 12.73 cm

The area= πr^2

Substitute

Area= 3.142* 12.73^2

Area= 3.14*162.0529

Area= 508.85 cm^2

Also the diameter is two times the radius

Diameter= 2*12.732

Diameter= 25.46cm
