Answer:
= 36
Step-by-step explanation:

(3×2)(3×2) = (6)(6)
= 6^2
= 36
If you solve for radius you get 7. Therefore the diameter of the cone would equal 14.
Answer:
(a) 
(b) 
Step-by-step explanation:
Given
Variation: Inverse proportional.
This is represented as:

See attachment for table
Solving (a):
First convert variation to equation

From the table:

So, we have:





Substitute 4 for k in 


Solving (b): x when y = 25.
Substitute 25 for y in 

Cross Multiply

Divide through by 25

Take positive square roots of both sides


∠FEG is an exterior angle.
An exterior angle of a triangle is equal to the sum of the opposite interior angles, so
2x + x = x + 40
3x = x + 40
3x - x = 40
2x = 40
x = 20
m∠FEG = x+40 = 20+40 = 60°
