I knew there was a formula for this, but did not remember it and so had to look it up. The formula is:
A = pi*r*(r + sqrt(h^2+r^2) )
Here, A = 3.14(4 ft)(4 ft + sqrt(36 + 16) = 140.9 square feet.
When in doubt about a formula, look it up!
Answer:
4(x+x+1+x+2)=156, x=12
Step-by-step explanation:
let the numbers be x, x+1 and x+2.
Now,
4(x+x+1+x+2)=156
4(3x+3)=156
divide both side by 4
3x+3=156/4=39
subtract 3 from both sides
3x=39-3
3x=36
divide both sides by 3
x=36/3=12
x=12
Hence, the smallest of the integers is 12.
The 3rd Image defines a piecewise function because for it to be a function, every input must match to exactly one and only one output. In Images 1, 2, and 4, there are certain inputs that have two outputs or stated otherwise, have two y-values for the same x-value. Only the 3rd Image matches 1 x-value to every 1 y-value. So, that's your answer.
You didnt list any graph?? Can you add it please :)
