it is a diameter. To calculate the chord length, you need to know the radius and either the central angle or the perpendicular distance to the center. The central angle of a chord is the angle formed
(i) Find the length of a chord which is at a distance of 12 cm from the centre of a circle of radius 13cm. (ii) The length of a chord is 16 cm of a circle of diameter 2 cm. find the perpendicular distance of this chord from the centre of the circle. ...
题目Circle M alongside has a radius of 10 cm, chord KL=10 cm and KP=PL.Calculate the length of MP. Leave your answer in the simplest surd form, if necessary. 相关知识点: 试题来源: 解析 Hence, The measure of MP is 8.66. MP=√ ((MK^2-KP^2))=√ ((10^2-5^2))=8.66Hence...
