The price of a pair of pants was reduced from $30 to $12. By what percentage was the price of the pair of pants reduced?

Well to calculate percentage decrease

(Starting value- ending value / starting value)* 100

so 30-18=12

12/30= 2/5

2/5*100= 200/5

40 percent

Now thats the amount lost so

100%-40%=60%

60% reduction

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
