D. 14π/3

Answer 2

Are you trying to find the arc length?

Answer 3

Calculate the length of the arc bound by the given central angle.

Answer 4

\[arc length = radius*angle\]
Where the angle is in radians, not degrees.

Answer 5

\[\angle(radians) = \angle(degrees)*\frac{ \pi }{ 180 }\]

Answer 6

840

Answer 7

Err, what? First, convert your angle to radians, keeping the pi. Then, multiply by the radius of the circle.

Answer 8

140 x 6/180

Answer 9

Err, no you mixed up the order. The radius is the distance from the center of a circle to its boundary.

Answer 10

\[arc length = 6*140\frac{ \pi }{ 180 }\]

Answer 11

i got 840

Answer 12

oh ok my bad

Answer 13

Well, I guess the order doesn't matter since multiplication is associative, but that isn't correct.

Answer 14

Simplify the \[\frac{ 140\pi }{ 180 }\] to its simpliest form. Then multiply the 6 in the numerator.
