So if you know the radius, then you know that pi*(radius^2) equals the area, so if we know the area, then we could just do a little bit of rearranging of the equation, here's the steps. You can find an area by drawing a shape on graph paper, and counting the squares inside the shape. If r is the radius of a circle, then r 2 is a square with sides of length r.

Let’s further examine the formula for area of a circle, a = • r 2. A simple way to go about this is to draw such a circle on graph paper and count. In the first supplied diagram above, ∠por =600 ∠ p o r = 60.

Unlike squares or rectangles, circles don’t have any straight sides. Test your understanding of area and perimeter with these % (num)s questions. Use grid paper to find the area in this lesson you will learn how to measure the area of a shape by using grid paper.

Area of a quadrilateral on a grid. Interactive, free online geometry tool from geogebra: The area of a circle is pi times the radius squared (a = π r²).
