C = 2<span>πr
C = 2 * 3.14 * 5.1
C = 32.028
You can round that to A. 32.03, because if the decimal after 2 is greater than it, then you round it to the number which is higher than it, which is 3. </span>

Step-by-step explanation:
40 degrees, then 40/360
40/360 is equal to 1/9

just find r and multiply all together, thats my best answer cause my IQ is like 60
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.
