prove that the slope of a straight line is not zero
What is the displacement of Point C to A. You can consider the diagram a semi-circle and a triangle
Diagram is a cone: Triangle on top and semi circle on bottom in the middle semicircle in the middle of the circumference it is point C . The Triangle legs are 8 cm and when they touch is A. The semicircle radius which is also the base of the triangle is 6 cm.
