Not my homework - my teenage sons and Mr Spudqueen is working away - so please help if you can! waste management Incapacity Benefit. Answers. 1 to 3 of 3 . Best Answer... Caution when calculating the area of a sector: n must be positive is less than 360° Example #1: A circle has a radius of 5 cm. Calculate the area of a sector when the angle made by the radii is 60°

**How do you work out the angle of a sector of a circle? in**

the angle in radians × the radius In the general case, the length s, of an arbitrary arc which subtends an angle θ is rθ as illustrated in Figure 4. r r s θ Figure 4. The arc length s, is given by r × θ This gives us a way of calculating the arc length when we know the angle at the centre of the circle and we know its radius. Key Point arc lengths = rθ (note: θ must be measured in how to write a science investigation The calculations would begin with a sector area of 52.3 square centimeters being equal to: (θ ÷ 360 degrees) × πr 2 . Since the radius (r) equals 10, the entire equation can be written as:

30/08/2018 · To calculate the radius of a circle by using the circumference, take the circumference of the circle and divide it by 2 times π. For a circle with a circumference of 15, you would divide 15 by 2 times 3.14 and round the … how to be a housewife when you work full time The chord meaures the curve of a sector of a circle? The height is what? The height from the center of the circle or the height from the ends of the chord? I have a book listing many formulas, but none to help knowing just the length of the arc and the height. Take a look at the following diagram, and point out all the information you know and I can supply the correct formula. My guess is you

## How To Work Out The Radius Of A Sector

To calculate the area of a segment bounded by a chord and arc subtended by an angle θ , first work out the area of the triangle, then subtract this from the area of the sector, giving the area of the segment. (see diagrams below)

- the angle in radians × the radius In the general case, the length s, of an arbitrary arc which subtends an angle θ is rθ as illustrated in Figure 4. r r s θ Figure 4. The arc length s, is given by r × θ This gives us a way of calculating the arc length when we know the angle at the centre of the circle and we know its radius. Key Point arc lengths = rθ (note: θ must be measured in
- The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
- The calculations would begin with a sector area of 52.3 square centimeters being equal to: (θ ÷ 360 degrees) × πr 2 . Since the radius (r) equals 10, the entire equation can be written as:
