Si α=60º; d=9 metros, la altura del edificio es A. √3

3

B. 9√3

C. 3√3

D. 4√3​

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)

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

step-by-step explanation:

the answer is 128

i believe it's a.

i'm not sure on this one, most likely correct.
