Answer:
≅217.82
Step-by-step explanation:
The volume of a cone of radius 4 is one third the area of the base B multiplied by the height (13).
therefore;
V = 1/3πr²h
Substituting the values in the equation gives;
V = 1/3π(4)²(13)
V ≅ 217.82 cubic units
Answer:
Prob.3
Denote r: radius of circle O
Formula for calculating AOB sector:
Area = pi*r^2*angle/360
Area = pi*r^2*45/360 = 18 pi
=> r^2 = 18*360/45 = 144
=> r = 12
For prob.4, give it a try, follow the formula I gave. Good luck !
