WebIf mAD =70 and mBC =40, find m∠AED. 6 In the accompanying diagram of circle O, chords AB and CD intersect at E, mAC =50, and mBD =150. Find m∠AED. 7 In the accompanying diagram, AB is a diameter of circle O and chord CD intersects diameter AB at E. If mAD =100 and mAC =40, find m∠DEB. 8 In the accompanying diagram, chords AB and CD ... WebThe equation for diameter of a circle from circumference is: d=c/\pi d = c/π. If written instead in terms of the radius, the diameter is very simple; it's just twice as long: d = 2r d = 2r. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) Area is the space contained within the circle's boundaries.

WebMay 2, 2024 · Explanation: ABCD can be considered as two triangles back to back. The sum of the internal angles of a triangle is 180o. So the sum of the internal angles of ABCD = 2 × 180o = 3600 Also ∠A+ ∠C = 180o = ∠B + ∠D ⇒ 2x + (3x −5) = 1800 = (x + 5) + ∠C 5x −5 = 180 Add 5 to both sides 5x = 185 Divide both sides by 5 x = 185 5 = 37 WebWe know that the central angle is 10 degrees. So you have 10 degrees over 360 degrees. So we could simplify this by multiplying both sides by 18 pi. And we get that our arc length is equal to-- well, 10/360 is the same thing as 1/36. So it's equal to 1/36 times 18 pi, so it's 18 pi over 36, which is the same thing as pi/2. WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different formulas for finding the circumference: C = πd. C = 2πr. cryptopp sha512
