If a circle has a diameter of 11.5 feet, what is the area?

Mathematics

3 0

Answer:

103.87 ft.

In this case, area equals \pi r^2

The diameter is 2r

But before worrying about anything else, we must start the problem. Let's do that now.

The first step is to find the broken-down form of the area.

A = \frac{1}{4} \pi d^2

Next, break this equation into a solvable definition.

\frac{1}{4} * \pi  * 11.5

Lastly, solve this equation, and round.

A ≈ 103.86891~ft^2

I'll mark u brainliest for the right answer and 15 POINTS!!!
morpeh [17]

The sum of all angles in a regular octagon is 1080 degrees. Because all sides are the same (regular octagon), all of the eight angles are the same too, so we simply divide 1080 by 8 and that is the solution.

1080/8 = 135

Which of the following is the solution set to the inequality −25x+14>20?
Bezzdna [24]

Answer:

Option C. x < -15

Step-by-step explanation:

<u><em>The correct inequality is</em></u>

-\frac{2}{5}x+14 >20

Solve for x

subtract 14 both sides

-\frac{2}{5}x+14-14 >20-14

-\frac{2}{5}x >6

Multiply by -1 both sides

\frac{2}{5}x < -6

Multiply by 5/2 both sides

x < -6(\frac{5}{2})

x < -15

andy was given data to draw 3 scatter diagrams B , which line of best fit should have not been drawn explain your answer
Lemur [1.5K]

Answer:

A line of best fit can only be drawn if there is strong positive or negative correlation. The line of best fit does not have to go through the origin. The line of best fit shows the trend, but it is only approximate and any readings taken from it will be estimations.
