At the beginning of the year, we discussed that students should be able to solve problems the way that works for them. Solve the problem below using the formula of your choice:

fraction of the circle x circumference = arc length

OR

arc length = 2*pi*r*angle/360

or

pi*d*angle/360 .

Problem: Find length of minor arc AB.

Image result for arc length problem

Show or explain your steps and the benefits of the formula you chose.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
