Answer :

The measure of 1.57 radians is equivalent to approximately 90 degrees.

To convert radians to degrees, we can use the formula:

Degrees = Radians * (180 / π)

Given that :

we need to convert 1.57 radians to degrees,

we can substitute the value into the formula:

Degrees = 1.57 * (180 / π)

To find the approximate value in degrees, we can use the value of π as 3.14:

Degrees = 1.57 * (180 / 3.14)

Degrees ≈ 89.68

Rounding this value to the nearest degree, we get:

Degrees ≈ 90

Therefore, the measure of 1.57 radians is approximately 90 degrees.
