Tangent of a Circle - GCSE Maths - Steps, Examples & Worksheet
WebSo we can write the formula for the circumference of a circle as: \ (C = \pi d\) However, the diameter is equal to \ (2 \times radius\), (\ (2r\)), so we can also write this formula as: \ [C = 2 \pi r\] It does not matter which of these formulae you use. But you must be careful to use the correct length for the formula (the radius or diameter). WebExample 1: standard diagram. Points A A, B B, and C C are on the circumference of a circle with centre O O. DE DE is a tangent at point A A. Calculate the size of angle BAD B AD. Locate the key parts of the circle for the theorem. Here we have: The angle BCA=52°. B C A = 52 ° BCA = 52°. BC A = 52°. duffryn yard engine shed
