Question

#13 Graph a circle with center (0,0) that passes through (0,-3). Find the area and circumference, both in terms of  PIE (3.14...) and to the nearest tenth.

Answer 1

Draw a diagram.

 

The radius is 3. The diameter is 6

 

Circumference = 2πr

C = 6π

C = 18.85

 

Area = πr²

A = 9π

A= 28.27
