For the given shapes, we will draw a sketch
a) A cone
the sketch of the cone will be as follows:
The cone has a circular base of radius = r, and a height of (h) and has a flat surface and curved surface as shown.
b) The diameter of the circle:
The diameter is a line segment (d) that connects two points lying on the circle through the center of the circle
c) The radius of the circle:
The radius of the circle (r) is a line segment that connects the center of the circle and any point lying on the circle
