A.10 cm B.5 cm C.12.5 cm D.39.25 c The area of a circle with a diameter of 6 cm is: 28.27 cm2. Area of a Circle = (pi)(r^2) Diameter = 2r If the diameter of the circle is 12, then the radius has to be 6

* Count square centimeters inside circle and estimate the area. * Draw a square outside the circle. Calculate the area of the square. * Draw a square inside the circle. Calculate the area of the square. * Estimate the area of the circle by relating it to areas of the outer and inner circles. * Cut a small circle into 16 equal pie-shaped pieces If the circumference of a circle is 28.26 inches, then what is its diameter? R = 2 cm If the area of a circle is 12.56 square centimeters, then what is its radius For example, if the diameter is 20 inches, you would divide that in half and get 10 inches. Then, plug the radius into the formula for finding area, area = πr^2. Ten squared is 100, and 100 times π is 314.16. Therefore, the area of the circle is 314.16 inches squared A circle is an important geometric shape in our world and is very relevant to our everyday experiences. In this lesson, we will explore one aspect of the circle, the segment What the formulae are doing is taking the area of the whole circle, and then taking a fraction of that depending on what fraction of the circle the sector fills. So for example, if the central angle was 90°, then the sector would have an area equal to one quarter of the whole circle

Find the diameter of a circle with an area of 67671 square centimeters. x The diameter is 26 X centimeters * Solution for Find area of a sector of a circle of diameter 20 centimeters with central angle of 60*. What is the area of its corresponding segment? What is the Since you are asking for square metres I expect that you want the area of the circle. The area of a circle is given by. area = π r 2. where r is the radius and π is approximately 3.1416. The radius is half the diameter so you have a radius of 12/2 = 6 cm. You want square metres not square centimeters so you need to convert the radius to metres The area of a circle with a diameter of 8 centimeters is: 50.27 square centimeters
