Aryabhatta found area of circle as pi*d^2/4 which is equal to pi*r^2. He gave direct results in his book aryabhattiyam. He also stated volume of sphere as 1.776pi*r^3, which is approximately correct.
•Aryabhatta give formula of area without using pi .
•Formula shows relation between circumference , radius and area .
Formula :-
Area = 1/2 circumference × radius
•Circumference of a circle can be measured without using pi . We have to use thread and ruler method to know circumference .
•Radius can be found using scale .
•When you find circumference and radius , just input them into formula.
•One more advantage is that we can measure area without doing any complicated multiplication of radius squared with pi.
The only piece of information required to find the area of a circle is the radius of the circle. Once you know the radius of the circle, the area is simply the radius squared multiplied by pi (approximately 3.14).
area of what? circle is pie times the radius squared, rectangle is base times height, and a square is the side squared
It depends on how the triangle and the circle are related - information that was not provided in the question.
You use the information you're given, along with the facts and formulas you know about the geometry of a circle.
To calculate the area of a unit circle you should use the equation x2+y2=1. The unit circle equal area of 1. You can find out more information on the mathisfun website for deeper explanation.
Yes. A square with the same area as a unit circle.
Pi is used to find area and circumference of a circle.
The answer will depend on what information you DO have.

The question cannot be answered without additional information. Depending on the level of mathematics, it could be the angle subtended by the arc or its perimeter or area.
It depends on what information you have.

By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.
