Pi is the ratio of the circumference of a circle to its diameter (the diameter is two times the radius). the component of a circle is Pi*R^2 the place R is the radius. the component of a sq. is the dimensions of any section squared. There are 360 levels or 2Pi radians in a circle. those data may well be used to remedy the subject concerns. as an occasion, If the radius of a circle is given as Y – 5 and its circumference is 20*Pi, then via the 1st actuality: Pi = circumference / diameter = 20*Pi / 2*(Y – 5) 2*Pi(Y – 5) = 20*Pi Y – 5 = 10 Y = 5
