The area of the sector of the circle formed by the central angle is: 37.7 square units.
Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)
The measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.
A central angle of 120 is 1/3 of the total circle. Aea of a circle = pi x r2, so for this sector the area is (1/3)pi x r2 = (1/3)(3.14)(52) = 26.17
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
The area of the sector of the circle formed by the central angle is: 37.7 square units.
Not enough information is given to work out the radius of the circle as for instance what is the length of sector's arc in degrees
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
The radius is 8 feet.
Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
The area of the sector of a circle with a radius of 2 inches and an arc of 60 degrees: 2.094 square inches.

It depends on what information you have: the radius and the area of the sector or the length of the arc.
Area of a sector of a circle = (pi) x (radius)2 x (central angle of the sector / 360)
The area of the sector is: 221.2 cm2
The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)
