Answer: 128
Step-by-step explanation: 3 x -2 + 70 = 64 + -2 + 70 = 128
Surface area of cylinder = 2 x pi x r x h + 2 x pi x r*2
So 2 x pi x 4 x 11 + 2 x pi x 4*2 = 376.99

Answer:
The inverse function is f(x) = (x + 7)/2
Step-by-step explanation:
To find the inverse of any function, start by switching the x and f(x) values.
f(x) = 2x -7
x = 2f(x) - 7
Now solve for the new f(x). The result will be your inverse function.
x = 2f(x) - 7
x + 7 = 2f(x)
(x + 7)/2 = f(x)
