WebJan 24, 2024 · The area of a sector of a circle is the amount of space covered within the sector’s boundary. A sector always emerges from the centre of the circle. The semi-circle is also a sector of a circle. An arc and a circle chord bound the area of sector and segment of a circle. When we divide something into parts, each part is referred to as a segment. WebFeb 24, 2024 · The formula for finding the area of a hexagon is Area = (3√3 s2)/ 2 where s is the length of a side of the regular hexagon. [1] 2 Identify the length of one one side. If you already know the length of a side, then you can simply write it down; in this case, the length of a side is 9 cm.

Differentiated objectives: Developing learners will be able to calculate the area of a circle given its radius or diameter. Secure learners will be able to evaluate the area of a circle in terms of π. 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 = … clean factor carpet cleaning
