To find the area of a circle, you take pi times the radius squared, or A = pi r^2. Using this formula, you can find the area of a circle if you know the radius -- or the diameter -- by plugging in your values and solving for A. Pi is approximated as 3.
Example 3. Find the area of a semicircle? From the given figure: Solution: The area of the semicircle is one-half the area of a circle with a diameter of 40 feet. The radius of the circle is\( \frac{40}{2}=20 \)feet.
