Given:
A circle with center O.
.
To find:
The measure of arc MN.
Solution:
We know that,
The central angles in equal to the measure of the corresponding arc.
Therefore, the measure of arc MN is 130 degrees.
No, it is not.
4/7 ≈ 0.5714
3/5 = 0.6
Actually, 3/5 is greater than 4/7.
Another way you could do this is by multiplying 4/7 with 5/5 and by multiplying 3/5 with 7/7.
4/7 * 5/5 = 20/35
3/5 * 7/7 = 21/35
Have an awesome day! :)
The circumference of the circle in terms of pi, based on the area of the circle is 6 π.
<h3>How to find the circumference?</h3>
The area of a circle can be found by the formula:
= π x radius x radius
= π x radius ²
If the area of the circle is 9π cm², then the radius is:
= √9π cm²
= 3 π cm
The diameter of a circle is double the radius so the diameter is:
= 3 x 2
= 6 cm
The circumference of a circle is:
= π x diameter
= π x 6
= 6π

Answer:
43 1/12
Step-by-step explanation:
Add them together
First we have to have equal denominators
6 3/4 can also be 6 9/12
36 1/3 can also be 36 4/12
We add them to get 42 13/12
12/12 is 1 so we add 1 to 42 and get 43 1/12
Hope this helps
How come it’s a right triangle, I think you do a2+b2=C2. Therefore, you do 9.4 times 9.4 and then 15.1 times 15.1. So it will be 9.4 + b2=15.1. 88.36+ b2=228.01. Then you subtract that and it will be 139.65. Then you do square roots because you are trying to get rid of the second power. And the final answer is 11.81736011. How they told you to round it to the nearest tenth, I will be 11.8. I think this is the answer.
