Answer:
The circumference of the circle is 28.26 m.
The area of the circle is 63.585 
.
Step-by-step explanation:
To solve for the circumference of the circle, start by using the circumference formula of a circle, which is 
. However, 3.14 will be used instead of 
for this formula.
First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.
Next, plug in the radius into the formula, and the formula will look like 
. Then, solve the equation, and the answer will be 28.26 m.
To solve for the area of the circle, start by using the area formula of a circle, which is 
. However, 3.14 will be used instead of for this formula.
For the area, plug the radius into the formula, and the formula will look like 
. Then, solve the equation, and the answer will be 63.585 .
Answer:
I don't think you are asking a math question, but in my opinion you should choose a leader that you think would be responsible in a group, then tell them what the group needs to do.

Answer:
x = 90°
y = 40°
z = 40°
Explanation (Concepts) :
A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.
Workouts:
z + 90° + 50° = 180°
z = 180° - 90° - 50°
z = 40°
=================
x + 90° = 180°
x = 180° - 90°
x = 90°
==================
50° + 90° + y = 180°
y = 180° - 90° - 50°
y = 40°
Answer:
1287
Step-by-step explanation:
The answer is 1287 because we use the combintions formula.
13!/((13-5)!(5!)) = 1287
You will want to divide the shape up into different parts to solve this. For example, first I would take the top rectangle (24x5=120) and add the answer of that to the rectangle in the middle section (120+(11x10)=230). Then, I would add the very last rectangle at the very bottom of the total we have so far (230+(7x3)=251). Lastly, I would take the semi-circle and find its area ((3.14x2)^2)/2=19.7192). Then, add all of the totals together and get your answer of
= 250.7192km^2
*note, only put the number of decimals needed.
Thanks :)
