The circumference is 25.12 whats the approximate length of the circle's diameter?
Using the formula for circumference, the diameter can be found. The formula is C = Pi x D where Pi = 3.1416 and D = Diameter. C = Pi x D (sub with known numbers) 25.12 = 3.1416 x D (divide both sides by Pi) 25.12 ÷ 3.1416 = D 7.9959 = D
The circumference of circle exceeds its diameter by 94 cm.Find the radius of the circle?
Formula for Circumference of a circle is C = pdC = d+94 therefored+94 = pd1 + 94/d = p1 + 94/d = 3.142d = 43.884cmd = 2rr = 21.942cm, C = 137.884cmAll figures rounded to 3 decimal places
Is there is allow to use calculator in cie math olevels paper?
Yes. you can use a calculator in the P2 of the mathematics D (calculator version) O level paper but you are strictly prohibited to use it in P1. Also, there are a set of instructions you have to abide by while selecting the calculator for example it should be non-graphical and non-programmable. You can refer to the syllabus of this subject of Cambridge's site for further details.
