Question 957416: An open-cone has a circular base of radius 10 cm and a slant height of 20 cm. Draw a net of the cone and label its dimensions.
P.S: I did the solve the equation but I couldn't draw the net. Please help. Thanks!

You can put this solution on YOUR website!
To draw the net of a cone first draw a straight line and mark a point P (point of cone) Use this as center and draw a circle with radius S (slant height). The sector of this circle you need is given by circumference of base/circumference
of slant height circle , in this case
Angle=%28%2820cm%28pi%29%29%2F%2840cm%28pi%29%29%29%2A360degrees=180 degrees.
So draw a half circle with radius 20cm (slant height) and tangent to this half circle(touching edge to edge) draw a complete circle with radius 10cm. This is the base, the larger half circle is the sides, and the net is done.
