A circle with a diameter of 8 inches has a radius of 4 inches. To find the radius of a circle based on a given diameter, divide the diameter by 2. Consequently, to find the diameter, multiply the radius by 2.
Know MoreThe radius of a circle is defined as any line segment that connects to the center point of a given circle. The diameter, on the other hand, is any line segment that passes through the center point of a circle, extending from one end to the other. The diameter of a circle is always twice as long as a radius.
Learn more about ShapesThe length of an arc of a circle is obtained by using the formula L=?r?/180, where L is the length of the minor arc of the circle, r is the radius of the circle and ? is the angle made by the arc at the center of the circle.
Full Answer >The formula for a radius is the diameter of a circle divided by two. The radius of a circle is defined as the distance from the middle of a circle to any point on the edge of the circle.
Full Answer >The diameter of a circle is the length of a straight line going from one side of a circle to the opposite side. To measure the diameter, simply choose two points on the edge of a circle that are directly across from each other, and measure the distance between these points. You will need a measuring device to perform this task.
Full Answer >Find the diameter of a circle with a given circumference by solving for the formula "d=C/pi," where d is the diameter, C is the circumference and pi is 3.1459. For this problem, find the diameter of a circle that has a circumference of 18.8754 inches.
