Hello!

The formula for area of a circle is A= π*radius^2 (radius squared)

We are given the radius, so now we must input this into our formula.

I will use 3.14 for an approximate value of pi, I am not sure what the rules are for your mathematics class.

A= π*radius^2

  = 3.14*9²

  = 3.14*81

  = 254.34 yd²

∴ <em>About </em>254.3 yd²

I hope this helps, and best of luck!

Answer:

  180 days

Step-by-step explanation:

The formulas for the volume of a cone and a cylinder are ...

  V = πr²h . . . . . volume of a cone

  V = (1/3)πr²h . . . . . volume of a cylinder

Comparing these formulas, you can see that the 6' high cone at the top will have the same volume as a cylinder of the same radius that is 2' high. So, we can simplify the problem to finding the volume of a cylinder that is 66+2 = 68' high.

  V = π(12 ft)²(68 ft) = 9792π ft³ ≈ 30752.5 ft³

When the corn is used at the rate of 170 ft³/day, it will last ...

  (30752.5 ft³)/(170 ft³/day) ≈ 180.96 days

The corn will last 180 days.

_____

<em>Additional comment</em>

In scenarios like this, it is inappropriate to round up. There will be about 162 ft³ of corn left after 180 days, which is not enough for an additional day.

The sales tax for an item was $24.50 and it cost $490 before tax.
Ymorist [56]

The sales tax rate is 5%.

Step-by-step explanation:

Given,

Sales tax for an item = $24.50

Cost of item before tax = $490

Sales tax rate = \frac{Sales\ tax}{Cost\ of\ item}*100\\

Sales\ tax\ rate=\frac{24.50}{490}*100\\\\Sales\ tax\ rate=\frac{2450}{490}\\\\Sales\ tax\ rate=5\%

The sales tax rate is 5%.
