Help me answer this question

The perimeter is 96.78 Hope this helps! :D

Step-by-step explanation:

radius squared times pi is the diameter.

radius is 6

squared is a number times itself

6 squared is 6 times 6 which 36

pi is 3.14

36 times 3.14 is 113.04

since a 1/4 piece is missing, 113.04 divided by 4

that is 28.26‬

113.04 minus 28.26 is 84.78

the length and width of the slice missing is 6

6 plus 6 is 12

84.78 plus 12 is 96.78

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
