CHALLENGING CIRCLE ARC SECTOR WORD PROBLEMS
ACT Math: A Challenging Arc Length & Sector Area Problem
One of our more popular posts involves Arc Lengths & Sector Areas for circles. With that in mind, we thought we’d give you a challenging problem (well, really two problems) involving this topic. Give it a try and then scroll down for the answer. The circle below has its center at O and triangle AOB is equilateral with sides that are each 6

Sectors, Areas, and Arcs: Word Problems | Purplemath
In essence, they've given me the central angle of a sector and that sector's arc's length, and they've asked me for the radius. So I'll plug into the arc-length formula, and solve for what I need. (In this case, I won't need to use a conversion factor, because I can use the radian form for "two-thirds of a circle".
Sectors and Circles Problems
Problem 1Problem 2Problem 31. The formula for the arc length is given byarc length AB = r * angle AOB 2. arc length AB is given and is equal to 2r, hence2r = r * angle AOB 3. Solve for angle AOB to obtainangle AOB = 2 radians 4. The area of the sector is given byArea = (1/2) * angle AOB * r 2 = (1/2) * 2 * r 2 = r 2See more on analyzemath[PDF]

Applications of Arc Length and Sectors - CISD
Applications of Arc Length and Sectors A sector of a circle is a region of the circle bounded by a central angle and its intercepted arc. A proportional relationship exists between the central angle bounding the sector and the complete circle. You have previously discovered a function that could be used to predict the arc length of a
Arc Length and Area of Sectors | Passy's World of Mathematics
Apr 19, 2013If the Sector is shaped like a yellow Pacman, then it is a “Major” Sector. Eg. The large remaining section of Pizza in the above picture is a MAJOR sector, because it is between one half circle and a full circle in size. Quarter Circles and Half Circles are also “Sectors”. Sectors should be familiar to anyone who has ever drawn a Pie Chart.
Circles on SAT Math: Formulas, Review, and Practice
On rare occasions, you may get a word problem on circles because the question describes an inequality, which is difficult to show in a diagram. When given a word problem question, it is a good idea to do your own quick sketch of the scene.
