The hardest part of this would be finding the length of that arc. Though, since it's a quarter circle, it makes our job a whole lot easier.

The circumference of a circle is 2πr, therefore, a quarter circumference of a circle would be (2<span>πr) / 4.
</span>
Therefore, the length of that arc would be (2 * 3.14<span> * 8) / 4 = 12.56
</span>

With this figure, we can just add up the rest of the perimeter.

12.56 + 8 (circle radius) + 10 + 10 (two rectangle heights) + 17 (rectangle length) + 9 (rectangle length minus radius, for the top-right part of the rectangle), giving us an answer of 66.56cm

Matthew purchased a washer and dryer for $2,885 using an 18-month deferred payment plan with an interest rate of 26.12%. What is
-Dominant- [34]
For a deferred payment plan no interest is accrued for the deferment period.

If $85 is made each month, then in 18 months, 18 * 85 = $1,530 must have been paid off from the balance owed.

Thus, the remaining balance after the deferment period is $2,885 - $1,530 = $1,355.
