Area of a Circle Calculator – How to Find Area of a Circle with Area of Circle Calculator?
You can use the area of a circle calculator to get a calculation for area of circle and given its diameter or radius. Whether you’re looking for an area calculator of a circle or a radius to area calculator, you’ve come to the correct spot because our tool works both ways. We’ll walk you through the three most important bits of knowledge of the circle’s area, diameter, and radius. We’ll cover the formula for area of the circle, how to find the area of a circle and other areas of mathematics that make use of the same equation.
What is the Area of a Circle?
In math, a circle is a group of points on a plane that are all the same distance from a central point. Some things in the real world that are round are coins, pizza, dinner plates, and other foods. The radius measures how far the points are from the center. Half of the radius is the diameter. The circle is a closed, two-dimensional shape made up of points that are all the same distance from the center. The word “circle” comes from the Greek word “kirkos,” which means “ring.” We talked about what is a circle, how to calculating the area of circle, and the Area of the circle formula in this article.
Area of a Circle Formula – What is Area of a Circle Formula?
When a point moves around a fixed point at a fixed distance from the point, this is called a circle. A circle is a closed curve whose edge and center are the same distance from the center (Interior fixed point). The circle’s radius is the fixed distance from the fixed point (also called the center of the circle). Circles are all around us, like the sun, a ball, a round playground, and so on.
Now we know what a circle is and how to explain it using things we see every day. Let’s find out what makes up the circle. Here is a list of the parts of the circle. Before you learn the area of circle formula, you should know what its parts are. This will help you get a better grasp area of circle formula.
C*C/4*pi gives the Area of the Circle Calculation, where C is the circle’s circumference.
A circle’s diameter is the line that cuts it into two equal parts. We can also say that the diameter is just the circle’s radius times two, and we write it as d or D.
- D= R/2
Where,
D = Diameter
R = Radius
Best Ways – How to Find Area of a Circle?
One of the most common tasks in geometry class is to figure out the area of the circle from the information given. The basic area of the circle formula is A = 2, where r is the diameter of the circle. Since we were in school, we have used this formula. Here are three ways to figure out how much space a circle takes up.
Calculating the Area of Circle Radius – How to Find Area of the Circle with radius?
A circle’s radius is the distance from its center to its edge. The radius will be the same no matter how you measure it. A circle’s diameter is also twice its radius. Usually, you will be given a range. It will be hard to find the circle’s radius if the circle’s center isn’t marked. Say the edge of the circle is 14 cm away.
A = πr2
Example
We know that the circle’s diameter is 14 cm, so we can use this formula to figure out how big the circle is. And we know that is equal to 22/7, so we can use these numbers in the formula to find out how big the circle is.
A = 22/7*14*14
A= 616 Cm2
Calculating the Area of Circle with a Diameter – How to Find Area of a circle with Diameter?
It’s easy to figure out how big a circle is if you know its diameter. We know that the diameter is twice the radius, so if we know the radius, we can easily find the area of circle calculation.
A = πr2
We can put radius = 2* diameter
A = π(2d)2
Example
Let’s say that the diameter of the circle is 28 cm. Then find the area of circle. We know that is 22/7 and that it doesn’t have any units. We also know that a circle’s diameter is 28 cm.
A = 22/7(2*28)2
A = 9856 cm2
Calculating the Area of the Circle with Circumstance:
Here, we show you how to figure out the circle’s area by using its circumference. If we only know the circle’s circumference and not its radius or diameter, we can use the following formula to figure out the circle’s area.
A = C2/4π
Example
Let’s say that the circle is 7 cm around. Since we know the circle’s circumference, we can use the above formula to find its area.
A = C2/4π
A = 7*7/4*(22/7)
A = 3.89 cm2
So, we’ve gone over the three ways to figure out how big a circle’s area is. To figure out how big the circle is, the students have to use all three methods. We gave the students examples to help them understand. Students should look at the examples and try to do as much practice as possible.
