Circumference of a circle
2 answers:
Answer:
Multiply the radius by 2 to get the diameter.
Multiply the result by π, or 3.14 for an estimation.
That's it; you found the circumference of the circle.

Answer:
Step-by-step explanation:
the straight sides are just 4.5 *2 = 9 cm
the arcs are 2
r * Ф/360
where Ф= 50 for this problem
and r = 8
the inner arc is 2(3.5) *50/360 = 3.05432
the outer arc is 2(8)*50/360 = 6.98131
total is 19.0356
to 3 sig figs is 19.036 :)

Answer:
m is less than or equal to 12.2
Step-by-step explanation:
$3+$1.80(m) is less than or equal to $25.00
$1.80*12.2 miles= $21.96
$21.96+$3=$24.96
-1 - 8 / 2 + 1 = -9 / 3 = -3
-1 = -3(2) + b
-1 = -6 + b
Add 6 to both sides.
5 = b
y = -3x + 5
My work and the answer is shown up in the picture.
I used the substitution method to check my answers by using x and y into the two equations.
