A replica at the face of the full moon was created. If the diameter of replica is 9 feet. What is the area of the replica of the moon.
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle.
Since the diameter of the replica is 9 feet, the radius (r) is half of the diameter, so r = 9/2 = 4.5 feet.
Now we can calculate the area of the replica of the moon:
A = π(4.5)^2
A = π(20.25)
A ≈ 63.61 square feet
Therefore, the area of the replica of the moon is approximately 63.61 square feet.
