Since the diameter d d is equal to 2 2 times the radius r r, the formula for circumference using radius is 2πr 2 π r. Substitute the value of the radius r = 4.5 r = 4.5 into the formula for the area of a circle. Pi π π is approximately equal to 3.14 3.14
In a circle, points lie in the boundary of a circle are at same distance from its center. This distance is called radius. Circumference of a circle can simply be evaluated using following formula. Circumference = 2*pi*r where r is the radius of circle and value of pi = 3.1415 The circumference is a distance measurement that shows the length of the line that creates the outside of the circle. One simple way to find the circumference is to use a string and wrap it around a round object. The point where the string overlaps itself should be marked. When you straighten out the string, measure between the marked point and the end of the string to find the circumference The circumference is the distance around a circle. In other words, it's the perimeter of the circle. And we find the circumference by using the formula C = 2πr. Circumference of a Circle Formula. But what do we do if we only want to find a fraction or a part of the distance around the circle? We need the Arc Length Formula Correct answer: Explanation: The formula for the area of a circle is πr 2 . For this particular circle, the area is 81π, so 81π = πr 2.
