Hi I tried to attach an image but it never works for me.
I have figured out part (a) and part (B)(i)
Now I am on part B(ii): And it states to find the height.
I know that the circumference of the base is 44cm.
I know the radius of the base is 7 cm.
So I got help from someone and I saw that if you draw an actual cone the segment here forms a right angled triangle, of which would be the height.
I then thought I had this solved as the radius 7 cm, w2ould be the base of the triangle, and the bigger radius 10.5 cm would be the hypotenuse.
But my book says 12.6 cm is the answer for the height.
I get something else after using Pythagorean theorem.
I get 7.8cm.
