The construction of copying ∠"QPR" is started below. The next step is to set the width of the compass to the length of ("AB") How does this step ensure that the new angle will be congruent to the original angle?

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)
