A circle in maths or geometry is a 2DGeometric Shape, that can be defined as a locus of points that is equidistant from a fixed point known as the center for that circle. You can simply define a circle in maths as a round-shaped figure with no corners or edges. This article will mak...

Given the area of a circle is 64pi, how do you find the radius of the circle? How to find the area of a circle? How do you solve for the radius when the area of a circle is given to you? How do you calculate the radius of a semi-circle whe...
Example 3: Using the semicircle formulas, calculate the circumference of a semi-circle whose diameter is 8 units.Solution: To find: The circumference of a semicircle Given: The diameter of semicircle = 8 units Radius = 8/2 = 4 units Using the circumference of a semicircle formula, ...
A circle is a 2-dimensional closed shape that has a curved side whose ends meet to form a round shape. Learn about circles with concepts, properties, and examples.
Recall that area of a circle is πr², where: r is the radius of the circle. π is Pi with an approximate value of 22/7 or 3.14. So, the formula for calculating the area of a semicircle is: Area = ½ × πr² Recommended Worksheets More Worksheets Finding the Perimeter/Circu...
An ellipse is also called an oval and it is, essentially, an elongated circle. The distances from the center point to the side are not constant, which makes the formula for finding its area a little tricky. To use this formula, you must know: ...
For example points S and T lie on the exterior of the circle.All those points for which the distance is equal to that of the radius of a circle lie on the circle. For example points U and V lie on the circle.Semicircle:Semi means half, so semicircle is half a circle. It is ...
Now, we can do the same for circle S. But we can also see that it is a semi-circle. So instead of taking our circumference of2πrfor the whole circumference, let us just take the circumference of half (πr) and so save ourselves the trouble of all the steps we used for circle ...
The radius of incircle is given by the formula $r = \dfrac{A_t}{s}$ where At = area of the triangle and s = semi-perimeter.
