The surface area of a sphere is given by

where r represents the radius.
As the radius is given as 60 meters we replace r with 60 in the formula above to get the surface area.
Answer:
The y intercept is (0,-8)
Step-by-step explanation:
To find the y intercept, set x = 0 and solve for y
-4x -2y = 16
-4(0) -2y =16
-2y = 16
Divide by -2
-2y/-2 = 16/-2
y = -8
The y intercept is (0,-8)
I think It's 0.9% I'm not sure though or 1.03%
-3(-x)-6=-3x+10
-3 -3
(-x)-6=-3x+7
-6 -6
(-x)=-3x+1
i only got this far!! im so sorry!!
