@Mertsj Can you help me please or ask anyone to?
65 degrees is 65/360 of the entire circle. The length of the entire circle is 2 pi r. Find 2 pi r and multiply it by 65/360
Not the answer you are looking for? Search for more explanations.
6-inch radius central angle = 65 degrees Circumference = 2*PI*6 Circumference = 37.70 The arc would be (65/360) of the circle or 0.18055556 0.18055556 * 6 = 1.083333 Rounding pi to 3.14 would make the answer 1.08
The closest answer would 1.13 because it is closer

Wait I messed up answer is 0.18055556 * 37.70 = 6.806784 SORRY !!!
oh thank you lol

Here's a calcualtor to check it http://www.1728.org/radians.htm And I'll help with another
The point (−3, 1) is on the terminal side of angle θ, in standard position. What are the values of sine, cosine, and tangent of θ? Make sure to show all work.
I don't exactly know know specifically what they mean by terminal side, standard position. MAYBE it's that angle starts at (0,0)?
