The answer I get is different to that provided in SMQ8 (Secondary Maths for Queensland) Year 8. Would you please show me where I am wrong. I have been able to work out all the others in Chap 6.5. The question and my workings follow.
Calculate the length of the curved part... In the circle there are two curved areas, opposite each other, both have an angle of 45 degrees. Therefore the curved area is two times 45 degrees of the 360 circumference. Eg 90 degrees of 360 degrees that is one quarter. Next, an arrow showing radius of 15 cm. Circumference = 2radius x pie that is 2x3.14x15 = 94.2 Curved part = 94.2 x .25
My answer 23.5. Answer in book 84 cm I would appreciate your help MathsDaphne Williams 01:40, 24 February 2007 (UTC)
Hey
I want to create a wikipedia article, but I might need to draw some diagrams. What do people use to make stuff like pullback diagrams?
