Answer:
4 feet
Step-by-step explanation:
From the question, we are given;
- Height of the cylinder as 20 ft
- Volume of the cylinder as 320 pi
We are required to find the radius of the cylinder fish tank;
- We need to know that the volume of a cylinder is given by;
Volume = pi × r² × h
Rearranging the formula;
r² = V ÷ pi × h
Therefore;
r² = 320 pi ÷ (pi × 20 ft)
= 16
Thus;
r = √16
= 4 ft
Therefore, the radius of the fish tank is 4 feet.
This would be:-
square root [ (5-0)^2 + (-9 -3)^2) ]
= square root ( 25 + 144)
= sqrt 169
= 13 Answer
Since radius is 5, equation is:
