The angles shown are
PR is the bisector of angle P
So
4x+30=90
4x = 60
x = 15
answer is B. 15
The volume of the cylinder by definition is given by:
V = Ab * h
Where,
Ab: base area
h: height
Substituting values we have:
140 = Ab * 12
To find the area, the first step is:
Pass the 12 dividing.
Answer:
the correct first step in finding the area of the base of a cylinder is:
Pass the 12 dividing.
