If the perimeter of minor sector OAB is 55 cm, and the radius of the circle is 7 cm, the valueof ∠ AOB isA. 110∘B. 45∘C. 450∘D. 180∘ Consider the following statements : 1. If two chords AB and AC of a circle are equal, then the centre of the circle lies on the angle bisector of angle CAB. 2. If two concentric circles are intersected by a line at A, B, C and D respectively, then AC = BD. Which of the above statements is/are correct? Find the area of the shaded region in the given figure, where a circular arc of radius 6 cm has been drawn with vertex O of an equilateral triangle OAB of side 12 cm as centre. Solution: OAB is an equilateral Triangle with side 12 Circle with radius of 6 Each angle of an equilateral triangle is 60° Angle at the centre in segment, θ = 60°The length of the sector = (θ/360°)× 2πr. l = (40°/360°) × 2 × (22/7) × 7. l = 44/9 units. Example 2: Find the area of the sector of a circle if the radius of the circle is 20 units, and the length of the arc is 8 units. Solution: Given, radius = 20 units and length of an arc of a sector of circle = 8 units. We have a circle with centre O and two radii OA and OB. If the perimeter of minor sector OAB is 55 cm, and the radius of the circle is 7 cm, the valueof ∠ AOB isA. 110∘B. 45∘C. 450∘D. 180∘ AB is a chord in the minor segment of a circle with centre O. C is a point on the minor arc (between A and B). The tangents to the circle at A and B meet at a point P. If ∠ACB = 108°, then ∠APB is equal to: Q10. A circle is inscribed in ΔPQR touching the sides QR, PR and PQ at the points S, U and T, respectively. PQ = (QR + 5)cm, PQ = (PR ...Find an answer to your question OAB is a sector of a circle of radius 12 cm Angle AOB= 60º Work out the length of the arc B. Give your answer in terms of pie. DeadlyKiller269 DeadlyKiller269 07/12/2020 Mathematics ... Since 60° is one sixth of the entire circle (360°) it means that the length of arc B is 1/6 th of the circumference. ... mad movies hdbritish lab vs english labge 100 amp thin breakerherbal empire k2 paper for salehow old is whoppa with the choppaland cruiser gx vs zxb3yond hackhomes for sale bathgatepulse electric scooter 12v 80w1920s bathroom sinkhow to change roblox password without emailhow to know if someone hide their instagram story from youamore teabest golf tempo drillstrulieve free delivery1978 kenworth w900a partsmars conjunct mc transittbc holy priest leveling guiderescue dogs gippsland victoriareno flooding todayold colony ymca missiongaming cursor installation xp
