Area of semicircle = πr 2 /2 For instance. we can calculate the surface area of a sphere. a cone or even the surface area of a cylinder.
In The Case Of A Circle. The Formula For Area. A. Is A = Pi * R^2. Where R Is The Circle’s Radius.
To find the area of a quarter circle. just divide the area of the full circle by four. The diameter of a circle calculator uses the following equation: Formula to calculate surface area (s.a.) of a circle.
A = C2 / 4Π.
The formula for finding the area of a full circle is πr 2. where r represents the radius of the circle. Or. when you know the circumference: The unit of area is the square unit. such as m2. cm2..
After Simplifying This. We Get The Area Of The Circle As Πr 2.
Sssa 2 = πr2 2. \(\pi r^2\) means \(\pi \times r \times r\). Yet. with just the diameter. or half the diameter (the radius). or even only the circumference (the distance around). you can calculate the area of any circle.
Since We Know That A Semicircle Is Half Of A Circle. We Can Simply Divide That Equation By Two To Calculate The Area Of A Semicircle.

Finding The Perimeter And Area Of A Quarter Circle.
Since the pizza is divided into 4 equal parts. each part is a quarter circle and hence its area can be found by using the area of a quarter circle formula. Area semicircle = area circle / 2 = πr² / 2 the area of a semicircle is just a half of the area of a full circle. Therefore. the area of the semicircle is πr 2 /2.
