y=45x+200
y is the total cost, x is the number of months, and 200 is the start.

</span>f(-3)=3(-3) -(-3)^2
f(-3)=-9 - 9
f(-3)=-18
answer is the last one on the picture
We need the radius to find the surface area. Since we have the circumference we can use that to find the radius.
C = 2πr
23 = 2(3.14)r
23 = 6.28r
23/6.28 = r
3.66 = r
Now use the radius to find the surface area.
SA = 4πr²
SA = 4(3.14)(3.66)²
SA = 168.33
Surface area is C. 168 cm²
Hope this helps :)
