How do you find the radian
WebFeb 3, 2024 · 1. Set up the formula for the area of a sector. The formula is , where equals the area of the sector, equals the central angle of the sector in degrees, and equals the radius of the circle. 2. Plug the sector’s area and central angle into the formula. This information should be given to you. WebFor any amount of radians, whole or decimal, positive or negative, you just multiply by [180/pi] to get degrees. So 0.9 * 180 / pi ~= 51.57 deg.

The radius of a circle from circumference: if you know the circumference c, the radius is r = c / (2 * π). The radius of a circle from diameter: if you know the diameter d, the radius is r = d / 2.
WebAnswer: At 2m, one steradian cuts through 2×2 = 4 m 2 of the sphere. And because the sensor is relatively small, its flat surface area is approximately the area of sphere that it occupies.
