Answer:

I think the answer should be 54 pi centimeters but I can't see all the options, area of a circle is pi r^2 so if the diameter is 18, diameter = 2r so the radius is 9. pi 9^2 is 81 pi, then the same for the 3 unshaded ones and just subtract the area of the 3 white circles (27 pi) out of 81 pi.

$10,000 at an annual rate of 7%, compounded semi-annually, for 2 years
forsale [732]

Answer:

\$13,107.96

Step-by-step explanation:

Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.

Therefore, we can set up the following equation to find the new balance after 2 years:

\text{New balanace}=10,000\text{ (old balance)}\cdot 1.07\cdot 1.07\cdot 1.07\cdot 1.07,\\\text{New balanace}=10,000\cdot 1.07^4=\boxed{\$13,107.96}
