Answer:

16.12 inches

Step-by-step explanation:

To find the arc length of a circle, you can use the formula 2\pir(θ/360)

θ is the central angle

Substitute Pi for 3.14

Substituting the numbers in the equation, we have 2 × 3.14 × 14 × \frac{66}{360}

Put this equation into a calculator and you will get 16.118667, which can be simplified to 16.12 inches.

A parabola has a vertex at the origin. The equation of the directrix of the parabola is y = 3. What are the coordinates of its f
mylen [45]

Answer:

(0, -3)

Step-by-step explanation:

The vertex is halfway between the directrix and the focus.  The vertex is at (0, 0) and the directrix is a (0, 3).  There are 3 units between them, so that means that the focus is 3 units the other way at (0, -3).

In the triangles, TR= GE and SR=FE. If GF= 3.2 ft, which is a possible measure of TS?
Marina86 [1]

Question:

In the triangles, TR = GE and SR = FE. if GF = 3.2 ft, which is a possible measure of TS? 1.6 ft 3.0 ft 3.2 ft 4.0 ft

Answer:

The correct option is;

3.2 ft

Step-by-step explanation:

Here, since two sides of the triangle are equal, then the third side can also be equal.

From the available options, we have;

3.2 ft which will make the triangles TSR and GFE to be similar.

We check that the three sides of both triangles are then equal as follows

TR = GE

SR = FE

GF = 3.2 ft = TS

Hence, triangle TSR will meet the requirements of a perfect triangle.
