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

Q: What is the area of the sector formed by central angle of 120 degrees and a radius of 5?

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.

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.

If each sector has a central angle of 30 degrees then 360/30 = 12 sectors

If each sector has a central angle of 30 degrees then 360/30 = 12 sectors

The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm

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.
