**Circle Geometry What is a Circle DK Find Out**

A circle can be folded into two halves that are exactly the same, which means that it is symmetrical. The line of this fold is an important part of the circle, called the diameter. One half of this line (from the center to the edge of the circle) is known as the radius.... Now let's find the perimeter of the other semicircle that had the diameter of 10 feet. In this case, we're given the diameter. We've discovered, though, that the radius is simply half the diameter

20/06/2014 · i need to find the area of the shape at the top of the original diagram posted but because its not a semi circle im not sure how to approach it The question is confusing, the diagram is confusing, however I suspect that at least one of your questions can be answered by looking at:. the area formula in particular.... First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and … the area of a circle is pi times the radius squared.

We've discovered, though, that the radius is simply half the diameter... 14/05/2018 · To find the radius from the perimeter, you need to know that the perimeter (also called "circumference" when talking about a full circle) of a full circle is given by 2*pi*r. Since we need the perimeter of a semicircle instead of a full circle, divide this by 2 (since the arc length is half…
