256π units² (answer b)
step-by-step explanation:
the formula for the surface area of a sphere of radius r
is a = 4πr²
and so, if r = 8 units, then the surface area is:
a = 4π(8 units)² = 256π units² (answer b)
- both graphs increase on their domain.
- the graphs of both functions have the same x-intercept.
- neither graph has a y-intercept.
a: inscribed angles
