The formula to find the circumference of a circle given the information we know (the diameter), you could use the circumference formula of c=pi*diameter or:
c=3.14 * 4
c=12.56 is the circumference IF THE CIRCLE WAS WHOLE, but since we're working with a semicircle (and in this case, what looks to be exactly 1/2 of a circle), you could divide 12.56 by 2 and come up with 6.28 as the circumference of each of the semicircles.
49.5
To figure this out you have to multiply the percent times the number but remember to change the percent when multiplying by moving the decimal two places to the right. There fore the equation would be .88•56.25=49.5
There is missing data here. We have the rate and principal amount but no value given in terms of years.
The formula needed is A = p(1 + (r/n))^(nt).
