Find the length of the common chord of two circles of radii 15 cm and 20 cm, whose centers are 25 cm apart.Choices:- 24 cm 25 cm 15 cm 20 cm
Question
Solution 1
To solve this problem, we can use the formula for the length of the common chord of two circles, which is given by:
Length of common chord = 2 * sqrt[(r1^2) - (d^2/4)]
where r1 is the radius of the smaller circle and d is the distance between the centers of the two circles.
Here, r1 = 15 cm and d Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
