Step-by-step explanation:
< DBC (angle DBC)
I think that the answer is C
To solve for radius use the volume formula and solve for r.
V = πr²h
320π = πr²(20)
320π/π = 20r²
320 = 20r²
320/20 = r²
16 = r²
√16 = r
4 = r
Answer is D. 4 feet.
Hope this helps :)
You can solve this by algebraically as well as graphically. When I tried both ways I got:
solution is x= -2<span />
