Alenkasestr [34]

Answer: C=2\pi r

Step-by-step explanation:

Let be "C" the circumference of the circle (in feet) and "r" the radius of the circle (in feet).

Based on the information provided in the problem, you know that the circumference of the circle is always 2\pi as large as its radius.

Notice that this indicates a multiplication. Then, this means that the circumference of the circle is always equal to 2\pi by "r".

Based on this, you can write the following formula that expresses the circumference "C" in terms of the radius "r":

Please help:<br> In Δ ABC, sin A=88, sin B=42, and a =17, find the length of b.
iren2701 [21]

Answer:

Step-by-step explanation:

Use the law of sines.

Cross multiply.

bsin88 = 17sin42\\b = 11.38
