WebArea of a Sector. Say we have the same section of a circle, but we now wish to calculate the area of the sector. For a circle with radius \textcolor{red}{r} and angle … WebSTEP 1. Find any two radii in the circle and follow them to the circumference. STEP 2. See if there are lines from those points going to any other point on the circumference. If you are asked for a reason in an exam and you use this theorem, use the key phrase; "The angle at the centre is twice the angle at the circumference ". WebRadius = 6cm6cm. 2 Find the size of the angle creating the sector. Angle = 90°90° (shown by the symbol of the right angle). 3 Substitute the value of the radius and the angle into the formula for the area of a sector. Area of a sector = θ 360 × πr 2360θ × πr2. = 90 360 × π × 62= 36090 ×π × 62 = 9π= 9π. 4 Clearly state your answer. test team lead jobs
