Answer:
40π feet
Step-by-step explanation:
Using the diameter of a circle you can find the circumference much easily than the radius. To find circumference with diameter you would do π×d or in this case π*40 which would give you the answer 40π.
If the interest is the same for both accounts then:
.03x=.05(16000-x)
.03x=800-.05x
.08x=800
x=10000, since the interest is the same for both we can just double the interest from one investment to find the total interest earned each year...
.03(10000)2=$600.00
