Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. 5y2 − 8y = 2 11.2, –9.6 0.22, –1.82 3.64, –0.44 1.82, –0.22

Y= 1.82, –0.22

Step-by-step explanation:

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)
