The length of the radius of circle o is 18 cm.
<h2>
</h2><h2>
Given that</h2>
Circle o has a circumference of 36π cm.
<h3>
We have to determine</h3>
What is the length of the radius, r?
<h3>According to the question</h3>
Circle o has a circumference of 36π cm.
The length of the radius of the circle is determined by the following formula;
![\rm Circumference = 2\pi r](https://tex.z-dn.net/?f=%5Crm%20Circumference%20%3D%202%5Cpi%20r)
Substitute all the values in the formula;
![\rm Circumference = 2\pi r\\ \\ 36\pi =2\pi r\\ \\ r = \dfrac{36\pi }{2\pi }\\ \\ r = 18 \ cm](https://tex.z-dn.net/?f=%5Crm%20Circumference%20%3D%202%5Cpi%20r%5C%5C%0A%5C%5C%0A36%5Cpi%20%3D2%5Cpi%20r%5C%5C%0A%5C%5C%0Ar%20%3D%20%5Cdfrac%7B36%5Cpi%20%7D%7B2%5Cpi%20%7D%5C%5C%0A%5C%5C%0Ar%20%3D%2018%20%5C%20cm)
Hence, the length of the radius of circle o is 18 cm.

Answer:
106
Step-by-step explanation:
you take 82 and 24 and add them together so it would be like this 2 + 4 = 6 and 8 + 2 = 10 so the 8 is in a tens place so the answer from adding 8 + 2 = 100 because you in the tens place so the final answer would be 106 after adding it all up.
Answer:
Where is the triangle?
you might have to add a picture or a worded problem
Step-by-step explanation:
Ah clever. So you need two formulas.
1) Volume of the marble.
4(pi)r^3/3
= 4(pi)(1.4)^3/3
<span>= 11.49 (approx)
</span>
2) Formula for density.
D = M / V
= 9 / 11.49
= 0.78
0.78 < 1
Therefore the marble will float.
False, I don't think it makes any sense.
