Answer:

The formula to calculate the area of a circle is:

Area = π × (radius)^2

Given the diameter (D) is 22 centimeters, the radius (r) is half of the diameter:

r = D / 2 = 22 / 2 = 11 centimeters

Now, plug the radius into the formula:

Area = 3.14 × (11)^2

Area = 3.14 × 121

Area = 379.94 square centimeters

The circle's area is approximately 379.94 square centimeters.

Answer:

approximately 379.94 square centimeters.

Explanation:

To find the area of a circle, you can use the formula:

Area = pi * (radius)^2

Since the diameter of the circle is given, you can find the radius by dividing the diameter by 2:

radius = diameter / 2

Substituting the diameter value, you get:

radius = 22 / 2 = 11

Now, you can find the area by substituting pi and the radius value:

Area = 3.14 * (11)^2 = 379.94 sq. cm (rounded to two decimal places)

Therefore, the area of the circle is approximately 379.94 square centimeters.
