Answer:
V = 20πr²
Step-by-step explanation:
In this question, volume of the cylindrical tank has been defined as,
Volume V of the tank = Product of π, the square of the radius of the tank 'r' and the length of the tank 'h'.
Therefore, formula to calculate the formula will be,
V = πr²h
If the length of the cylindrical trailer is,
h = 20 feet
Then the volume of the trailer will be,
V = πr²(20)
V = 20πr²

Step-by-step explanation:
Answer:
72.2%
Step-by-step explanation:
Given data
Initial price= £245
Final price= £883
% increase= Final - Initial / final *100
% increase=883 - 245 / 245 *100
% increase= 638 / 883 *100
% increase=0.722*100
% increase=72.2%
Hence the increase is 72.2%
Each classroom donated around 320 cans(or more) of food.
320x28=8,960.
Let the width be w, then length = 2w - 1
Area = length times width = w(2w - 1) = 21.
Thus, 2w^2 - w = 21 or 2w^2 - w - 21 = 0
Solving the quadratic equation gives that w = 3.5.
Therefore, width is 3.5 ft and length is 2(3.5) - 1 = 6 ft.
