How to find area of a circle

## How to find area of a circle # How to find area of a circle There's no better way to figure out the area of a circle after you've drawn it than to use a calculator and do the math. But here's a fun method in case you want to try it!Report your result. Remember that a calculation of area is going to be reported in “square” units. If the radius was measured in centimeters, the area will be in square centimeters. If the radius was measured in feet, the area will be in square feet. You should also know whether to report your result using the symbol.

## Area The most common error when using diameter is forgetting to square the denominator. If you don't divide the diameter by 2 to find the radius, you can still find the area of the circle. However, you need to change the formula so that you square the 'd' otherwise your answer will be wrong. (Source:Learn the revised formula. If you know the circumference of a circle, you can use a revision of the formula for the area of a circle. This revised formula uses circumference directly, without the radius, to find area.

(If you're asking how to convert from square inches to square feet, divide the number of square inches by 144 to get square feet.)The area of a circle can be calculated in intermediate steps from the diameter, and the circumference of a circle. From the diameter and the circumference, we can find the radius and then find the area of a circle. But these formulae provide the shortest method to find the area of a circle. Suppose a circle has a radius 'r' then the area of circle = πr (Source:www.cuemath.com)

## Circle Radius: The distance from the center to a point on the boundary is called the radius of a circle. It is represented by the letter 'r' or 'R'. Radius plays an important role in the formula for the area and circumference of a circle, which we will learn later.Circumference: The circumference of the circle is equal to the length of its boundary.

This means that the perimeter of a circle is equal to its circumference. The length of the rope that wraps around the circle's boundary perfectly will be equal to its circumference. The below-given figure helps you visualize the same. The area of a circle is the amount of space enclosed within the boundary of a circle. The region within the boundary of the circle is the area occupied by the circle. It may also be referred to as the total number of square units inside that circle. (Source:www.cuemath.com)
