Solved The Diagram Shows A Sector Of A Circle With Centre O Chegg The diagram shows a sector of a circle with radius rcm and centre o. the chord ab divides the sector into a triangle aob and a segment axb. angle aob is θ radians. (i) in the case where the areas of the triangle aob and the segment axb are equal, find the value of the constant p for which θ=psinθ.2 (ii) in the case where r. The area of a sector with a central angle α = 90° of a circle with radius r = 1 is π 4. to calculate this result, you can use the following formula: a = r² · α 2, substituting: r = 1; and. α = 90° · π 180° = π 2. thus: a = (1² · π 2) 2 = π 4. notice that this is also a quarter of the area of the whole circle. Example 1: calculate the arc length (quadrant) calculate the arc length of the sector shown below. give your answer to 3 decimal places. find the length of the radius diameter. the radius of a circle is the length of the line segment from the centre of the circle to the circumference. here the radius = 6cm6cm.
