Circumference = 2piR= 2(Pi)(27)
Distance travelled is the circumstance multiplied by the 20 revolution:
Distance = 2(Pi)(27)(20)= 3 392.92 inches
9514 1404 393
Answer:
10%
Step-by-step explanation:
We assume the "sum" being referred to in both cases is the principal amount invested. The simple interest formula tells you ...
I = Prt . . . . . . interest on P invested at annual rate r for t years
We have ...
Filling in these values, we get ...
0.3P = Pr(3)
0.1 = r . . . . . . . . divide by 3P
The interest rate is 0.1×100% = 10% per year.
