**Semi Circle Geometry Semicircle Math@TutorCircle.com**

Half of the circle is called semicircle. The diameter of a circle splits it into two equal halves forming two semicircles. The area of the semicircle formula uses radius of the circle.... For evaluating the Arc Length of semicircle, we use following formula– Arc length of semi circle (s) = (radius / 2) * central angle, Suppose we have a semi circle, whose radius is 7 inches and central angle is 60 degree, then –

**Plotting a Circle Using a Line Graph in MS Excel? Yahoo**

So, the formula you’ll have to use to find the area of a semi-circle is πr 2 /2. Now, just plug “5 centimeter (2.0 in)” into the formula to get your answer. You can either use the closest approximation for π with your calculator, substitute 3.14 for π, or you can just leave the symbol in place. Here’s how you do it:... Area of Sector = θ 2 × r 2 (when θ is in radians) Area of Sector = θ × π 360 × r 2 (when θ is in degrees) Area of Segment. The Area of a Segment is the area of a …

Introduction to semi circle formula: Draw a circle on a piece of paper. Plot the center of the circle. Draw a line through the center of the circle and cut it along the line.... Area of Sector = θ 2 × r 2 (when θ is in radians) Area of Sector = θ × π 360 × r 2 (when θ is in degrees) Area of Segment. The Area of a Segment is the area of a …

It is a semi-circle. By only studying this part of the circle, it makes it a function. It now passes the vertical line test. Circles are not functions!

### Arc Length Formula. The arc length is the distance along the part of the circumference that makes up the arc. The following diagram gives the formulas to calculate the arc length of a circle for angle measures in degrees and angle measured in radians.

- Recently Added Math Formulas If we chop it in half to get a circle, then the volume is the area of the circle times 2/3rd of the major axis. (The major axis is the maximum length from the one end to the other.) However if we have a sphere and squash it to make a shorter fatter shape (a bit like a burger). In such case it is called an oblate ellipsoid. If we chop it through the middle to
- The area A of any triangle is the product of its inradius (the radius of its inscribed circle) and its semiperimeter: A = r s . {\displaystyle A=rs.} The area of a triangle can also be calculated from its semiperimeter and side lengths a, b, c using Heron's formula :
- Since a semicircle is just half of a circle, the area of a semicircle is shown through the formula #A=(pir^2)/2#. We can solve for #r# to show an expression for the radius of …
- A circle is all of the points that are a fixed distance, known as the radius, from a given point, known as the center of the circle. Explore the standard equation of a circle using …
