C. 4.45 cm. you take the circumference and divide it by pi to find the diameter
The complement of 31° is the angle that when added to 31° forms a right angle (90° ).
F(g(2))
g(x) = x^2 - 6x - 7
g(2) = 2^2 - 6(2) - 7
g(2) = 4 - 12 - 7
g(2) = -15
f(x) = x + 8
f(g(2) = f(-15) = -15 + 8 = -7 <==
ur answer is -7
