After remodeling the circular deck, the Museum Board Members decided to also build a circular fence around the existing playground for safety reasons. The diameter of the entire circular fence is 102.8 feet, while the radius of the playground is 37.3 feet. Determine the difference in areas of the two regions. Show your work and justify your reasoning.

answer: c i think

step-by-step explanation:

c.   x=2.4cm

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.
