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.
4(16) = 4(10+6) = 40 + 24 = 64
The answer is 1.59090909 but rounded to the nearest tenth would be 1.6.
Answer:
Therefore there are 10 ways to walk in xy space from (0,0) to (2,3).
Step-by-step explanation:
To move from (0,0) to (2,3) one has to walk 2 step along x-axis and 3 steps along y-axis.
One can chose 2 steps along x-axis and then 3 steps along y axis
Or,
2 steps along y-axis ,1 step along x-axis , 1 step along y-axis,1 step along x-axis
And so on.
This is a permutation of(2+3) things where 2 and 3 are two types of kinds.
The required permutation is
Therefore there are 10 ways to walk in xy space from (0,0) to (2,3).
