Find the area of a sector of a circle with radius 12 and arc length 10pi?

The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.


How do you find the degrees sector of an circle?

It depends on what information you have: the radius and the area of the sector or the length of the arc.


To find the area of a sector you multiply the area of the circle by the measure of the arc determined by the sector?

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


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.


To find the area of a sector you multiply the area of the circle by the fraction of the circle covered by that sector?

That would certainly do it.


Find the area of the sector when the sector measures 10 degrees and the diameter of the circle is 12?

For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.


What is the formula used to find the area of a sector?

area of sector = (angle at centre*area of circle)/360


True or fulse To find the area of a sector you multiply the area of the circle by the measure of the arc determined by the sector?

Finding the length of sector AB your central angle is 75 and the radius of the circle is 36 For some reason 23.6 is the only answer that comes up.?

A sector of a circle is a part of a circle formed by two radii and the arc they intercept; it is a fractional part of a circle. So that the question should be, "find the area A of the sector OAB ...".There are 360⁰ in a circle. So the area of the 75⁰ sector is 75⁰/360⁰, or 5/24, the area of the circle.A = (5/24)(pi )(362) ≈ 848.23 square units.


How do you find an area of a sector of a circle?

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


A sector of a circle has a central angle of 50 and an area of 605 cm2 Find the radius of the circle?

If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm


How can you find the measure of the central angle with the sector area known?

It is found by: (sector area/entire circle area) times 360 in degrees
