Find the circumference and area of each circle. Round to nearest tenth.

Short Answer

Expert verified

CircumferenceC=12.6mAreaA=12.6m2

Step by step solution

01

Step 1. Radius of the given circle.

In the given circle, observe that the radius is 2 m, that is,r=2m

02

Step 2. Formula used.

The circumference and area of a circle of radius r are given by

CircumferenceofacircleC=2蟺rAreaofacircleA=蟺r2

03

Step 3. Calculate the circumference of the circle.

In order to find the circumference of the circle, use the above formula and substitute 2 for r and simplify further as shown below:

CircumferenceofcircleC=2蟺2C=12.6m

04

Step 4. Calculate the area of the circle.

In order to find the area of the circle, use above formula ad substitute 2 for r and simplify further as shown below

A=蟺22A=4蟺A=12.6m2

Therefore,

CircumferenceofgivencircleC=12.6mAreaofgivencircleA=12.6m2
