Olivia is told that the circumference of a circle is equal to 8π. How can she use this value to calculate the area of the circle without first finding the radius of the circle?
A. Olivia should divide the given circumference by 4π to find the area of the circle.
B. Olivia should divide the given circumference by 4π and then square the result to find the area of the circle.
C. Olivia should square the given circumference and then divide by 4π to find the area of the circle.
D. Olivia should divide the given circumference by 2π to find the area of the circle.
B. Olivia should divide the given circumference by 4π and then square the result to find the area of the circle.
The formula for finding the area of a circle using the circumference is A = (C^2) / (4π), where A is the area, C is the circumference, and π is pi. By using this formula, Olivia can calculate the area of the circle without finding the radius first.
