Question

The diagram shows a sector of a circle of radius 10 cm .
A)find as a multiple of pi
the straight edges are brought together to make a cone.
calculate (B) the radius of the base of the cone
(c) the vertical height of the cone

Answer 1

Answer: h=6 cm

Step-by-step explanation:rc  length  =  10 * 8pi/5

=   16pi

This is the circumference of the base

(a)   2pir     =   16pi  where  r  =  radius of base

 2r     =    16

  r     =  8 cm

(b)   10^2    =   h^2   +  8^2

h^2    =   100  -  64

 =    36

h      =    6 cm
