Formula for the circumference of a circle:

C = 2πr     (C = circumference      π(pi) = 3.14.....    r = radius)

You know:

r = 9 cm      

π = 3.14       So substitute/plug it into the equation

C = 2πr

C = 2(3.14)(9)

C = 56.52 cm

Simplify the expression b - 7 + b - 8
natulia [17]

Answer:

2b - 15

Step-by-step explanation:

b - 7 + b - 8  

You combined the two b's correctly, but didn't combine the two constants, -7 and -8.  

Those combine to   -7 + (-8)  = -7 - 8  = -15,  so the final answer is

2b - 15

you have -7 and are subtracting 8 more, so you are moving 8 units left on the number line, so it has to get more negative.
