Question

What is the arc length of a circle that has a 6-inch radius and a central angle that is 65 degrees? Use 3.14 for π and round your answer to the nearest hundredth.
- 0.65 inch
- 1.13 inches
- 6.80 inches
- 390.01 inches

Answer 1

@Mertsj Can you help me please or ask anyone to?

Answer 3

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

Answer 4

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

Answer 5

The closest answer would 1.13 because it is closer

Answer 6

Can you help with another

Answer 7

Wait I messed up
answer is
0.18055556 * 37.70
= 6.806784

Answer 11

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.

Answer 12

I don't exactly know know specifically what they mean by terminal side, standard position.
MAYBE it's that angle starts at (0,0)?
