Answer:
$613.04
Step-by-step explanation:
<em>Compound Interest Formula:</em>
n = number of compounds
t = time
r = interest rate
P = principle amount (original amount)
A = final amount
Since it's compounded quarterly, that means there will be 4 compounds per year, so n=4. The interest rate has to be converted to the decimal value, and this is done by simply dividing it by 100 to get r=0.06.

I think it’s 196? base 1 +base 2=28 radius is 7 but we need the whole thing so 7x2=14.
then multiply and then divide by 2 28X14= 392 divided by 2 = 196
