1. Starting at sunrise the temperature rose 2.5' every hour. After 8 hours, the temperature was 67". Write an
equation to model the temperature, y, after x hours after sunrise.
Equation: ?

A. y=2.5x+47. B. 62 degrees

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)
