The given cube .
The expression for the volume of the sphere is,

Thus, the volume of the sphere is 261 cubic-m.

Find the the amount of interest per year. Since $567 were earned over 6 years, you divide the interest earned by the number of years it took to accumulate it:
$567/6 years = $94.5/year
Divide that by the interest rate which the interest rate needs to be in decimal form:
$94.5/.0525 = $1800
