true

The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)

Area of whole circle = pi*r2 = 64*pi Area of Sector = Area of Whole Circle * Angle of Sector/Angle of Whole Circle = Area of Whole Circle * 120/360 = Area of Whole Circle / 3 = 64*pi/3 = 67.0 to the nearest tenth.

The area of the full circle is (pi) R2 = 64 pi.We call a full circle "360 degrees".The 300-degree sector is (300/360) = 5/6 of the full circle, so its area is(5/6) x (64 pi) = 167.55 square units (rounded)

Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o

sector

That would certainly do it.

Divide the area of the sector by 360 and multiply it to the area. The area of the sector is 5 square inches.

Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].

Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].

Sector

Divide the angle sector by 360 and multiply it by 24 square meters. The area is equal to 3 square meters.
