In any given circle the measure of a n
WebJul 3, 2024 · You can calculate the circumference of any circle if you know either the radius or diameter. The formulas are: C = πd C = 2πr. where d is the diameter of the circle, r is its radius, and π is pi. So if you measure the diameter of a circle to be 8.5 cm, you would have: C = πd C = 3.14 * (8.5 cm) C = 26.69 cm, which you should round up to 26.7 cm WebSep 15, 2024 · Find the radius r of the inscribed circle for the triangle ABC from Example 2.6 in Section 2.2: a = 2, b = 3, and c = 4. Draw the circle. Figure 2.5.8 Solution: Using Theorem 2.11 with s = 1 2(a + b + c) = 1 2(2 + 3 + 4) = 9 2, we have r = √(s − a)(s − b)(s − c) s = √(9 2 − 2) (9 2 − 3) (9 2 − 4) 9 2 = √ 5 12 .

(Plz like and rate so they know it's the correct answer) WebJust as the full circumference of a circle always has a constant ratio to the radius, the arc length produced by any given angle also has a constant relation to the radius, regardless of the length of the radius. This ratio, called the radian measure, is the same regardless of the radius of the circle—it depends only on the angle.
