O B. 37.7 in
C. 9.4 in
D. 18.8 in

18.8

Step-by-step explanation:

C =2*pi*r

C = 2*pi*3

C=18.8

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
