Question

80° is equal to ___ radians

Answer 1

180 degrees is equal to
`\pi` radians.

Set up the following proportions:


`(80)/(x) = (180)/(\pi)`

Cross multiply to get the following equation:

180x = 80
`\pi`

Divide both sides by 180 to solve for x.

x =
`(80)/(180)\pi`

The answer is
`(80)/(180)\pi` radians, simplified to 1.4 radians.
