WebPractise using pi to calculate various circle measurements. Menu Level 1 Level 2 Level 3 Level 4 Level 5 Level 6 Exam Help More This is level 5; the radius and angle subtended at the centre of the circle are given, find the length of the arc or area of the sector of the circle. Give your answers correct to three significant figures. Weby = (x – 7)² – 5 has a tuning point of (7, -5) ⇒ Change sign on -7 to +7 and -5 stays the same. To find the y intercept ⇒ set x = 0 and solve for y. Completing the square involves changing the way a quadratic equation is written. We complete the square to make it easier to draw parabolas (U-shaped curves).

Arcs and Sectors National 5 Maths Maths.scot
WebCircles are 2D shapes with one side and no corners. The circumference is always the same distance from the centre - the radius. Sectors, segments, arcs and chords are different parts of a circle. WebAn arc is a section of the circumference of a circle. Continue A sector is a part of the interior of a circle, bounded by an arc and two radii. Continue Finally, a segment is a part of the interior of a circle, bounded by an arc … WebThe area of the sector AOB is 28 cm 2. (a) Find the radius of the circle, giving your answer correct to 2 decimal places. We know the area and the angle and want to find the radius so we will need to substitute the information into the formula for the area of a sector and solve to find the radius. Substitute A = 28 and θ = 42° into the ... cd 冬の歌
