To find the area of a circle, you use the formula A = πr^2, where A is the area and r is the radius of the circle. Since the diameter is 8 yards, the radius is half of that, which is 4 yards. Plugging this into the formula, we get A = π(4)^2 = 16π square yards. So, the area of the circle is 16π square yards.

Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
What is the sum of a center angles of a circle
Circumference of any circle = (pi) x (diameter) Circumference of this particular circle = (pi) x (70 yd)
3.141*18 yd = 56.538 yd Circumference is 2 * pi * r
False because it is the other way around in that if the diameter is 18 yards then the radius is 18/2 equals 9 yards.
