Question

Find the circumference and area of the circle to the nearest hundredth. Use 3.14 for . Round to the nearest hundredth if necessary.

The circumference of the circle is about ____ cm.
The area of the circle is about ____ cm2.
Please answer!

Answer 1

The circumference of the circle is about 166.42 cm.

The area of the circle is about 2205.07 cm².

Explanation:

Diameter = 53 cm

Radius = r = 53cm/2 = 26.5 cm

π = 3.14

Circumference = C = 2 π r

C = 2(3.14)(26.5cm) = 166.42cm

The circumference of the circle is about 166.42cm.

Area = A = π r²

A = (3.14)(26.5cm)² = 2205.07 cm²

The area of the circle is about 2205.07 cm².
