Given:
Radius = 7cm
Central angle (theta) = 40 degrees

Asked:
Arc length (s)

SOLUTION:
s = 2*pi*radius*(central angle/360)
s = 2(3.14)(7cm)(40 degrees/360 degrees)
s = 4.88 cm

Therefore, the arc length of the circle is 4.88 centimeters.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

-4 = x -1 can I see you work it out please?
kherson [118]
We need to get x alone, to do that we add 1 to both sides to cancel out the -1 on the right.
-4 = x -1
+1 +1
-3=x

This means x is equal to -3. Hope this helps!

natali 33 [55]

Answer:

250 minutes with the flat rate of $29.

x\leq 250

x would be the number of minutes called.

x-250

Tracy would be charged by $0.35 per minute.

f(x)=29\\ 0\leq x\leq 250

f(x)=0.35(x-250)+29,\\250\leq x\leq ∞
