Answer:
2.512
Step-by-step explanation:
the equation for circumference of a circle is
2(pi)r
plug in the 4
2(pi)4
combine like terms
8(pi)
you can leave the answer as is or you can multiply
8(3.14)= 2.512
the answer would be 2.512
***pi is equal to 3.14, if you are not allowed to keep your answer in terms of pi there is a pi button on the calculator you can use, or simply plug in 3.14
Answer:
C. there are no solutions because the slopes are the same and the y-intercepts are different.
step-by-step explanation:
y = 2/3x - 6
3y - 2x = 9
y = 0
3(0) - 2x = 9
-2x = 9
/-2 /-2
x = -9/2 = -4.5
x = 0
3y - 2(0) = 9
3y = 9
/3 /3
y = 3
(-4.5, 3)
slope 2/3
y-intercept (0, 3)
there are no solutions because the slopes are the same and the y-intercepts are different
