Question

Find the area and the circumference of a circle with radius 2m. use the value 3.14, and do not round your answers. be sure to include the correct units in your answers.

Answer 1

The area of a circle is given by:

`A_c = \pi r^2`
Plug and chug:

`A_c = \pi (2)^2 = 12.56m^2`

Circumference is given by (d = 2r):

`C_c = \pi d`
Plug and chug:

`C_c = \pi (4) = 12.56m`

Those are your answers!
