WebFind the area of a sector of a circular region whose central angle is 3 radians with a radius of 5 feet. Solution: The radius of sector $= r = 5$ feet. Angle of sector $= \theta = 3$ radians. If is measured in radians, then. The area of the sector $= \frac{\theta}{2}\times r^2 = \frac{3}{2}\times5^2 =37.5$ sq. feet. WebThere are 2π radians in a full angle (360°) 1 radian is equal to 180/π which is about 57.2958°. It is easy to measure angles in radians. All you do is determine the fraction of a circle the angle sweeps out and then multiply that by 2π. For example, a right angle sweeps out ¼ of a circle. So ¼ * 2π = ½π. philips sonicare hx9340 akku tauschen https://brain4more.com
