A sector of a circle of radius 8cm is bent to form a cone.find the radius of the cone and its vertical angle if the angle subtended at the centre by the sector is 280
Answered by oobleck
the base radius is r = 280/360 * 8
Now draw a diagram. You can see that the base angle θ is found using
cosθ = r/8 = 7/9
