If the arc on a particular circle has a length of 3 units, and the degree measure of the arc is 30o, which is the circumference
of the circle?
i got 12 but i am not sure if i did it right
1 answer:
The answer is not 12.
The ratio of the arc to the angle equals the ratio of the circumference to 360°.
Then 3/30° = circumferece / 360°
3/30 = x / 360 => x = 360 * 3/30 = 36 units.
Answer: 36 units

Answer:
3
Step-by-step explanation:
3.5*4.5=15.75 ft^2
15.75/5.25=3 bags
Solving
S = 3F - 24
for F gives
S + 24 = 3F
(S + 24)/3 = F
The best choice is the last one:
F = (S + 24)/3
The rational bumber between -2 and 0 is -1
Multiply 4.51 by 3.4
That's all it is asking you
