How do you get area of sector without given radius?
if given the central angle and the area of the circle, then by proportion: Given angle / sector area = 360 / Entire area, then solve for the sector area
Is the area of a sector the area of the circle multiplied by the fraction of the circle covered by that sector?
true
What is the area of a circle if the area of its sector is 49?
The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)
What is area to the nearest tenth of a 120 degree sector of a circle with radius of 8 ft?
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.
To find the area of a sector do you multiply the area of the circle by the measure of the arc determined by the sector?
No. Assuming the measure of the arc is in some units of length along the curve, you have to divide the result by the circumference of the circle. Basically, you need to multiply the area of the whole circle by the fraction of the whole circle that the sector accounts for.
