The diameter of a circle is 38 yards. What is the circle's area?
d=38 yd
Use 3.14 for 𝜋.
The radius (half of the diameter) of the circle is 38/2 = 19 yards.
The area of the circle is A = 𝜋r^2, where r is the radius.
Substituting the values,
A = 3.14 x 19^2
A = 3.14 x 361
A = 1,133.54
Therefore, the circle's area is approximately 1,133.54 square yards.
To find the area of a circle, you need to know its radius. The radius is half the diameter.
1. Start by finding the radius:
radius = diameter / 2 = 38 yards / 2 = 19 yards
2. Once you have the radius, you can calculate the area using the formula:
area = 𝜋 * radius^2
Plugging in the values:
area = 3.14 * (19 yards)^2
3. Calculate the area:
area ≈ 3.14 * 361 yards^2
area ≈ 1134.34 square yards
Therefore, the area of the circle is approximately 1134.34 square yards.
