    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.
