A circle is 360° all the way around; therefore, if you divide anarc's<span> degree measure by 360°, you find the fraction of the circle's circumference that the </span>arc<span> makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the</span>arc<span>.</span>
Answer:
i think the answer is 105.96
Simplify= 4r+3
Because 8r plus -4r which is 4r and then 3 can’t be simplified so u keep it the same
Then the answer if r=5 is 23
Because the equation looks like 4(5)+3
5 times 4 is 20 plus 3 is 23
Not sure I understand this but
5x+2=0
5x = -2
x = -2/5
Or
x = -.4
