Step-by-step explanation:
A>70*9
a>360
a should be at least 361
Answer:
2111.15
Step-by-step explanation:
A=2π*r*h+2π*r^2
You plug in your height and radius into the formula for surface area of cylinder
Substitute y=4x to the second equation:
x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1
When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4
Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.
