Answer:
47.1
Step-by-step explanation:
Circumference= d*pi OR Circumference= 2piR
With these equations in mind, we can multiply 7.5 by 2, to get 15, then multiply that by 3.14 for our final answer of 47.1.
Just look at the percentages and make them into fractions. You can think about it like money. 50 cents is half of a dollar, so %50 is 1/2. for the decimals, you just take the percent and put a decimal point in front of the answer, so 28% is .28, 50% is .50, 18% is .18. For fraction to decimals, you could just put 1 divided by 4 into a calculator and it will tell you .25, which is the decimal, and 25 cents is one fourth of a dollar, so it works out.
