Answer:
Step-by-step explanation:
The area of the base is given by the formula ...
A = πr²
so the radius is ...
r = √(A/π) = √(1386/(22/7)) = √441 = 21 . . . units
__
The volume is given by ...
V = (1/3)Bh
where B is the area of the base, and h is the height (equal to the radius). Filling in the numbers, we have ...
V = (1/3)(1386)(21) = 9702 . . . . cubic units
Not getting in to too much details but basically
Area of half circle - area of triangle
3.14r^2-1/2bh
r=6 b=12 h=6
