Solution: Radius; OA, OB, and OE ; PQ; Diameter and chord; Example 3: If a circle has a radius of 3 cm, what is the length of its longest chord? Solution: The longest chord is the diameter of the circle. Diameter = 2 × radius = 2 × 3 = 6 cm. Example 4: The minute hand of a circular clock is 21 cm long.

WebIn two dimensions the answer is simply: as the radius increases, the area increases by the square of the increasing factor. That's a bit abstract, so let's give some examples. If the radius doubles, that's a factor of 2. The square of 2 is 4, so if the radius doubles the area is multiplied by 4. This is the example given in the video. WebJun 14, 2024 · An angle is the union of two rays having a common endpoint. The endpoint is called the vertex of the angle, and the two rays are the sides of the angle. The angle in Figure 2.1.2 is formed from → ED and → EF. Angles can be named using a point on each ray and the vertex, such as angle DEF, or in symbol form ∠DEF.
