SECTOR AREA WORD PROBLEMS
Sectors, Areas, and Arcs: Word Problems | Purplemath
This inner area, forming a sector of a smaller circle, needs to be subtracted from the previous value, in order to find the area that is swept by the actual wiper blade. This smaller area, using the same angle measure but having a smaller radius (namely, 12 cm), is:Angular, Linear Velocity · Sectors, Areas, and Arcs
Sectors and Circles Problems - analyzemath
The area of the sector is given by Area = (1/2) * angle AOB * r 2 = (1/2) * 2 * r 2 = r 2; Problem 2 The angle of a sector in a given circle is 40 degrees and the area of the sector is equal to 20 cm 2. Calculate the arc length of the sector. Solution to Problem 2: The formula for the area of a sector is Area = (1 / 2) * angle of sector * r 2[PDF]
Section 5.1 (Word problems ) - Florida State University
Section 5.1 (Word problems ) 1) A central angle in a circle of radius 4 cm is 75ο the length of the intercepted arc in cm. (Ans: 3 5π) 2) Find the area of a sector in square cm of a circle of a radius 6 cm if the central angle is
Area of a Sector and Segment (solutions, examples
Comparing the area of sector and area of circle, we derive the formula for the area of sector when the central angle is given in degrees. where r is the radius of the circle This formula allows us to calculate any one of the values given the other two values.

Evaluate the following word problems. (Take π = 3 and round to the nearest hundredths) 1) Two circular discs of radii 5 cm and 4 cm are cut from a rectangular piece of card measuring 20 cm by 11 cm. Calculate the area of the remaining card. Area of remaining card = cm2 2) A circular floor has a radius of 9 m. The floor is to be waxed. A can of wax will cover 10 m2.
Circles - math-worksheet
We can use our knowledge about the area of a circle to help us find the area of a sector. We know that the area of a circle is given by A = pi*r^2 but if a sector is only a part of a circle, we can just find the area
