The diameter of a circle is 28 yards. What is the circle's area?
d=28 yd
Use 3.14 for 𝜋.
The radius of the circle is half of the diameter, so:
r = d/2 = 28/2 = 14 yards
The area of the circle is:
A = πr² = 3.14 x 14² = 615.44 square yards
Therefore, the circle's area is approximately 615.44 square yards.
To find the area of a circle, you need to use the formula:
Area = 𝜋 * (radius)^2
Since the given information is the diameter, you need to divide it by 2 to find the radius.
Radius = Diameter / 2 = 28 yd / 2 = 14 yd
Now you can substitute the value of the radius into the formula:
Area = 3.14 * (14 yd)^2
Calculating the squared radius:
Area = 3.14 * 196 yd^2
Finding the product:
Area = 615.44 square yards
Therefore, the area of the circle is 615.44 square yards.
