The semicircles below have a radius of 21 cm each. Taking π as 227, what is the total area?

The question seems to be incomplete as it does not provide an image or a clear description of the number of semicircles. However, I'll show you how to calculate the area of a single semicircle with a radius of 21 cm.

The formula for the area of a circle is πr². Since we're dealing with a semicircle (which is half a circle), the formula becomes 1/2πr².

Given: Radius (r) = 21 cm π = 22/7

Substitute these values into the formula:

Area = 1/2 * (22/7) * (21 cm)²

Calculate the area and that will be the area of one semicircle. If there are more semicircles, multiply this result by the number of semicircles to get the total area.
