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.

How to find the area of a circle. Need a custom math course? A = (π /4) × d2.

#### 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.
