WebJan 16, 2024 · You can use the area to find the radius and the radius to find the area of a circle. The area of a circle is the space it occupies, measured in square units. Given the area, A, of a circle, its radius is the square root of the area divided by pi: r=\sqrt {\frac {A} {\pi }} r = πA. The formula for radius to area is: A=\pi {r}^ {2} A = πr2. WebWhat is the measure of ∠BOA and ∠AOE in the circle shown below? Solution Since BE is a straight line (diameter of the circle) then, ∠BOA + AOE = 180° (x + 50) ° + (x + 10) ° = 180° 2x + 60°= 180° Subtract 60° on both sides. 2x = 120° By dividing both side by 2, we get x = 60° Now substitute. (x + 50) ° = 60° + 50° = 110° (x + 10) ° = 60° + 10° read 5

WebMar 26, 2024 · The first step in measuring the diameter of a circle is to gather a measuring device, such as a ruler, meter stick or yard stick. The measuring device should be larger than the diameter of the circle to obtain precise measurements. Place the measuring device on any point on the edge of the circle WebWe can say: Circumference = π × Diameter Example: You walk around a circle which has a diameter of 100m, how far have you walked? Distance walked = Circumference = π × … WebNow let's say you take a compass and draw a circle. You will be able to easily measure the diameter, however you will not be able to fold a strip of paper into a perfect circle, again it might be just a millimeter off.
