Sqrt 16 = 4...this is a rational number
Answer:
150°
Step-by-step explanation:
angle opp to 30° is also 30° (vert opp)
so x =150° as ab is parallel to cd so the angles are co-interior angles and thus x= 180°-30°=150°
Answer:
It is given that the volume of a cone =
cubic units
Volume of cone with radius 'r' and height 'h' = 
Equating the given volumes, we get
=


It is given that the height is 'x' units.
Therefore, 

Therefore, r = 3x
So, the expression '3x' represents the radius of the cone's base in units.
