WebLearn about and revise the different angle properties of circles described by different circle theorems with GCSE Bitesize AQA Maths. WebThe length of the arc of the sector need to be the same length as the circumference of the circle on the bottom of the cone. You just need to work out the length of the circumference of the circle and equate it to the length of the arc of the sector in terms of theta(the angle of the sector) and then solve for theta.

Web24 Mar 2024 · We are required to find the area of a grass lawn in ‘m 2 ‘ that has side length of 10 m and a subtended angle of π/2. Using the formula, we have Area lawn = 0.5 x (10) 2 x π/2 = 78.54 m 2. Exercise: Find the area of circular sector in ‘m 2 ’, that has perimeter of 100 cm with arc length of 40 cm. WebIn my opinion, the most important shape in maths is the circle. It’s so simple to understand, but it also gives us one of the most crucial constants in all of mathematics: p. Once we draw some lines inside a circle, we can deduce patterns and theorems that are useful both theoretically and in a practical sense. The defining feature of the ...
WebArea of sector of circle = (lr)/2 = (8 × 20)/2 = 80 square units. Example 3: Find the perimeter of the sector of a circle whose radius is 8 units and a circular arc makes an angle of 30° at the center. Use π = 3.14. Solution : Given that r = 8 units, θ = 30° = 30° × (π/180°) = π/6. Web4 Feb 2024 · 4. Quadratic Formula. x = − b ± b 2 − 4 a c 2 a. The quadratic formula helps you find the roots of a quadratic equation (parabola) if you can’t easily factor it. You need the quadratic to be in the form y = a x 2 + b x + c, and then you simply plug the coefficients and constants into the formula.
