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.
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.
The area of the circle is equal to the combined area of the rectangles formed by cutting the circle into equal-sized triangles and placing them together side by side. This is because the circumference of the circle is equal to the perimeter of the rectangles, which means the area enclosed by the circle is equal to the area of the rectangles. This concept is known as the "circle packing theorem" in mathematics.
You use the information you're given, along with the facts and formulas you know about the geometry of a circle.
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.
The formula for the area of a circle is πr^2, where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. So, "pi r squared" refers to the area of a circle, calculated by multiplying π by the square of the radius. This formula is fundamental in geometry and mathematics for finding the area enclosed by a circle.
