WebThis is the reasoning: A circle has an angle of 2 π and an Area of: πr2. A Sector has an angle of θ instead of 2 π so its Area is : θ 2π × πr2. Which can be simplified to: θ 2 × r2. Area of Sector = θ 2 × r 2 (when θ is in radians) Area of Sector = … WebArea between two concentric circles. From the figure, we can see that the outer circle has a radius of 5, and the inner circle has a radius of 2. Step 1: Calculate the area of the outer circle by ...
WebWe can find the answer by using this formula 4 ( π r 2 6 − 3 4 r 2) + 2 3 4 r 2 derivation of this formula is this- Just like triangle ABC we construct triangle CDB. We know that triangle ABC is an equilateral triangle because they are radii of same circle. Therefore angle ABC = … WebFrom the diameter and the circumference, we can find the radius and then find the area of a circle. But these formulae provide the shortest method to find the area of a circle. Suppose a circle has a radius 'r' then the area …
