Answer:
radius = 15 in.
circumference = 94.2 in.
Step-by-step explanation:
radius = diameter/2 = 30 in./2 = 15 in.
circumference = (pi)d = 3.14 * 30 in. = 94.2 in.

Answer:
The answer is B
Step-by-step explanation:
5x² +9x +3 - (6x ² -3x)
this is easier if you distribute the negative in front of the perenthesis so...
5x² +9x +3 + (-6x² + 3x)
then you just combine the terms with the same variable and exponent
-x² +12x +3
well, we know that π is 180°, so then what is 3π/5?
