Find the area ans the circumference of a circle with diameter 4m

Area:

The formula for the area of a circle is A=.  The problem gives the diameter (4); half of the diameter is the radius (r=2).

A=2π

A=6.2831m^2

Circumference:

The formula for the circumference of a circle is A=πd.

A=4π

A=12.5664m

Hope this helps!!
