Circumference from an arc
WebThe arc length is defined as the interspace between the two points along a section of a curve. An arc of a circle is any part of the circumference. The angle subtended by an arc at any point is the angle formed between the … WebThe arc width is 1500mm. The arc height is 2200 − 1950 = 250mm. Sam calculates the arc radius. radius = 250 2 + 15002 8 × 250. radius = 125 + 1125 = 1250. And it looks like this: Now Sam can mark out and cut the wood. Note: the formula comes from the Intersecting Chords Theorem, so h (2r-h) = (w/2) (w/2), can you work out the rest?
