Bianca's bank offers a savings account with a 2.1% APR, compounded monthly. The the actual annual percentage yield on this account can be calculated using i = (1+ r/m)^m, where i is the actual APR, r is the nominal interest rate and m the compounding period in a year. APR is equal to 2.12%

Travka [436]

Answer:

Step-by-step explanation:

We know that:

-measuring a cone
-diameter: 18 units
-height: 8 units

We need to know how to find the volume of this cone. To do this, we need the equation to find the volume of a cone:
$V= \pi r^2\frac{h}{3}$ where r=radius and h=height

Upon assessing this equation we also now know that we are missing a radius.

For a circle, the radius is the distance from the midpoint, center, to the border of the circle. The diameter is the distance from the border of one circle to another, passing through the midpoint. Knowing this, we can conclude that the diameter is two times the radius.

Using this information we can figure out the radius for this cone: 9 units.

Now that we have the radius, we can plug in the rest of the numbers with the correct placements.

$V= \pi 9^2\frac{8}{3}$ square the 9 by calculating 9 times 9.
