The diameter of a circle is 22 miles. What is the circle's area?
d=22 mi
Use 3.14 for 𝜋.
The radius of the circle is half the diameter, so:
r = 22 mi / 2 = 11 mi
The area of the circle can be calculated using the formula:
A = 𝜋r²
A = 3.14 x 11² = 380.26 square miles
Therefore, the area of the circle is approximately 380.26 square miles.
To find the area of a circle, you can use the formula A = πr², where A is the area and r is the radius of the circle. The radius is half the diameter, so in this case, the radius would be 22/2 = 11 miles.
Now, plugging in the values into the formula:
A = 3.14 * (11 mi)²
A = 3.14 * 121 mi²
A ≈ 380.14 mi²
Therefore, the area of the circle is approximately 380.14 square miles.
