Anthony rolled a six-sided die 138 times. Predict how many times you expect the die to have rolled on a 6?

It can be 23 or 823

Step-by-step explanation:

Depends because if you divide 138 and 6 you'll get 23.

If you multiply 138 times 6 you'll get 823  

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)
