The answer is D, 32pi
The radius is half the diameter, which is 32. The circumference equation is
or 
So that gives you 32pi
Answer:
457657657.2
Step-by-step explanation:
(762762762/5)*3=457657657.2 miles
Since the radius is 12, the equation is
.. x^2 +y^2 = 144
T: 8x+19
7x-2(4-2x)+6(5-x)-x+2-(6x+5) = 7x-8+2x+30+6x-x+2-6x-5 = 8x+19
Y: 56-8x
9-(-2-3x)+4(-x+6)-x+12-3(2x-3) = 9+2+3x-4x+24-x+12-6x+9 = 56-8x
