To calculate the area of a circle, you’ll need its radius, diameter, or circumference. Then, use one of the following formulas. Find Area Using Radius The radius of a circle is the length of a straight line from the center of the circle to the outer edge. The most commonly used form...
Find the area of the circle below to the nearest inch. To find the area of a circle, we need to find the radius first. The radius of the circle is half of the diamter which is half of 7 = 3.5 inches. Next we need to square the radius: 3.52= 3.5 x 3.5 = 12.25 cm. ...
Example 1:Divide the rectangle ABCD into unit squares, as shown. The area of a rectangle ABCD is the total number of unit squares contained within it. Thus, the total area of the rectangle ABCD is 48 sq. inch. Also, using this approach, we find that the area of a rectangle is always...
Properties of a Circle A circle is a round, symmetrical shape with no corners or sharp edges where each point along its edge is equidistant from the center. A circle has many properties, such as the radius, diameter, circumference, and area. ...
The area of a circle is basically the space coverage by the circle on a plane. The area of a circle is computed as- $$\text{Area of a Circle}~(A) = \pi r^{2} $$ where {eq}r {/eq} is the radius of the circle The circumference of the circle indicates a round path...
The area of a rectangle is the space occupied within the boundary of the rectangle. It is calculated by finding the product of the length and breadth (width) of the rectangle and is expressed in square units.
