how far from the centre of a circle is a chord of length 18cm if the radius is 15cm〜答案12cm求过程 答案 这个题的意思是,圆中一弦长18,圆半径为15,求圆心到弦的距离你自己画下图,也就是一个直角三角形,斜边长15,一个直角边为18/2=9,求另一个直角边的长度呗,用勾股定理就得12了相关推荐 ...
Calculate the area of the region inside the circle r = 4cos(theta) and outside the circle r = 2. Find the area outside of the circle r = 1 and inside the circle r = 2sin(theta). Sketch the area. If a circle has an area of { 49\pi } what is the radius of the circle? F...
From the above-mentioned formulae, it is possible to calculate the radius. r=C/2*π. Say, for example, you have a circle of circumference 28cm and you want to know the radius, you can find that by using the formula, r=28/2*π ...
If you only know the coordinates of the two points, you can still use the same formula mentioned above to find the radius of the circle. Make sure to use the coordinates to calculate the distance between the two points before plugging it into the formula. Can I find ...
