Simplify -b/2a where a=-6 and b=6

Write answer in reduced fraction

Step-by-step explanation:

-b/2a

a=-6 and b=6

-(6)/2(-6)

=1/2 or 0.5

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)

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
