If there was a circle and i wanted to find out the area.

what is the area of a circle with a radius of 5

The formula for the area of a circle is πr^2

r means radius.

If the radius is 5, then r = 5.

This means the equation for the area is π (5) ^2

π is about equal to 3.14.

So we can replace π with 3.14.

(3.14) (5) ^2

According to the order of operations, the first step to solve this is to do 5^2, which is exponents.

5^2 = 25

Next, multiply.

25 • 3.14 = 78.5

So the area of the circle with a radius of 5 is approximately 78.5 square units.
