Question

Find the circumference of 2 inches.

Answer 1

Is this for a circle with radius 2 inches, or diameter 2 inches?

Answer 2

Then the formula for a circumference of a circle is \[\pi*d=\pi*2=2\pi\]

where d = diameter, and that's just pi

Answer 3

or more specifically, \[2\pi\] inches to keep the units

Answer 4

Just find the area please.

Answer 5

Yes there is: The formula for area is \[2\pi*r^2\] where r = radius
Now you need to know that diameter = 2*radius
So d = 2r

Since d = 2
2 = 2r
r = 1

So the area is \[2\pi*r^2=2\pi(1)^2=2\pi \] in inches^2 as units
