Hey there!

We need to find the area of the hole. Let’s start off with the top rectangle. The sides are 11 and 3. Multiply the two numbers to get 33. Add the sqaure on the bottom. 3 x 2=6. Add the two shapes to get 39. The answer would be 39 ft 2.

I hope this helps!

The circumference of a circle is 11 pi inches.
ser-zykov [4K]

9514 1404 393

Answer:

  30.25π square inches

Step-by-step explanation:

You can use the formula for area in terms of circumference:

  A = C²/(4π)

  A = (11π)²/(4π) = (121/4)π = 30.25π . . . square inches

_____

You may be expected to find the radius first:

  C = 2πr   ⇒   r = C/(2π) = 11π/(2π) = 5.5 . . . inches

Then use the area formula:

  A = πr² = π(5.5 in)² = 30.25π in²

Which of the following is the equation for the graph shown?
Nina [5.8K]

The equation of the hyperbola is \frac{x^2}{4} -\frac{y^2}{12} = 1

<h3>How to determine the equation of the graph?</h3>

The points on the graph are given as:

  • (2, 0) and (-2, 0)
  • (4, 0) and (-4, 0)
  • Lines at: x = 1 and x = -1

The hyperbola can be represented as:

\frac{x^2}{b^2} -\frac{y^2}{a^2} = 1

The points (2, 0) and (-2, 0) means that:

b = \±2

Square both sides

b^2 = 4

So, we have:

\frac{x^2}{4} -\frac{y^2}{a^2} = 1

Also, we have:

a^2 = c^2 - b^2

Where c = 4

This gives

a^2 = 4^2 - 4

Evaluate

a^2 = 12

Substitute a^2 = 12 in \frac{x^2}{4} -\frac{y^2}{a^2} = 1

\frac{x^2}{4} -\frac{y^2}{12} = 1

Hence, the equation of the hyperbola is \frac{x^2}{4} -\frac{y^2}{12} = 1
