A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do you work out the area of a sector when given the length of the arc?

If you're only given the length of the arc, then you can't. You also need to know the fraction of the circle that's in the sector. You can figure that out if you know the angle of the arc, or the radius or diameter of the circle. -- Diameter of the circle = 2 x (radius of the circle) -- Circumference of the circle = (pi) x (Diameter of the circle) -- (length of the arc)/(circumference of the circle) = the fraction of the whole circle that's in the sector or -- (degrees in the arc)/360 = the fraction of the whole circle that's in the sector -- Area of the circle = (pi) x (radius of the circle)2 -- Area of the sector = (Area of the circle) x (fraction of the whole circle that's in the sector)


What is the area of a sector of a circle with central angle 140 degrees and radiusn6 inches?

The area of the whole circle would have been π*62 But instead of 360 degrees for the whole circle, the sector measures only 140 degrees. That is to say, the sector is 140/360 of the whole circle. Area = π*62*140/360 = 43.9823 sq inches.


What is the area of a sector of a circle that has an arc measure of 75 degrees and a diameter of 15.75?

Area of the circle = pi*7.8752 = 194.8278319 square units Area of sector = 75/360 times 194.8278319 = 40.58913165 square units

Find the area of the shaded sector if the sector is ten degrees and the diameter is 12?

area of whole circle = pi * radius squared = 3.14159 * 36 = 113.1area of sector = 113.1 * ( 10 / 360 ) = 3.14159 sq units


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)
