A circular pan has a diameter of 8 inches.

What is the exact area of the pan?

The area of a circle is calculated by multiplying pi times the squared radius, and the diameter is equal to 2 radius, so we have that the diameter is 8 in, therefore half of it is equal to the radius, that is:

radious = r = diameter/2 = 8/2

r = 4 in

then we express the area equation:

a = pi*r^2

a = (3.14) * (4) ^2

where we have substituted pi = 3.14 and radious, r = 4

a = (3.14) * (16)

a = 50.24

therefore the area is 50.24 squared inches
