Will mark bianleast What are the diameter and radius of a circle with a circumference of 32π ft?

d = 32 ft
r = 16 ft

d = 8 ft
r = 16 ft

d = 16 ft
r = 8 ft

d = 16 ft
r = 32 ft

r=16 ft , d =32 ft (a)

Step-by-step explanation:

c=2 pi r

32pi= 2 x pi x r

r=32 pi/2pi

r= 16

diameter = radius x 2

d= 16 x 2

d = 32

Sorry, the way this is written is a little confusing, but I’m assuming you mean the equation is x^2 + 18x + 12? Sorry if I’m mistaken. If this happens to be the case, then the a value would be 1, the b value would be 18, and the c value would be 12. Again I’m assuming this is in the ax^2 + bx + c formula. I hope this helps, sorry if I’m wrong :/
