In the last lesson, we learned that the formula for circumference of a circle is: . For simplicity, we use = 3.14. We know from the last lesson that the diameter of a circle is twice as long as the radius. This relationship is expressed in the following formula: . The area of a circle is the number of square units inside that circle. *Vals venezolano 3 antonio lauro sheet*The formula for the area of a circle (more properly called the area enclosed by a circle or the area of a disk) is based on a similar method. Given a circle of radius r , it is possible to partition the circle into sectors , as shown in the figure to the right. We always suggest to stick to only one formula for area of a circle which is one uses radius. When you are given with the diameter of the circle, just divide that value by 2 to get radius and use the first formula to find the area of the given circle. Hence the formula for area of a circle. Jul 26, 2019 · If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter. In the formula for area and circumference of a circle, radius plays an important role which you will learn later. Diameter The diameter of the circle is the line which divides the circle into two equal parts.

May 15, 2019 · In simple language, it is the rim of the ring. If we take a string and make a circle out of it, then the entire length of the string would give its circumference. Other than being able to solve problems given as homework, there are various practical applications for which we need to know how to find the circumference of a circle. DA has a length of 3.5 cm. CB is a diameter, since it has both endpoints on the circle and passes through the center of the circle. The diameter equals two times the radius, so the diameter of this circle is 7 cm, since 2 * 3.5 is equal to 7.
