Answer:
r = 22.3m circa
Step-by-step explanation:
We know that the perimeter of a circle can be calculated as follows:
p = 2r
So half of perimeter will be:
p/2 = r
We know that p/s = 70m, therefore:
r = 70m / = 22.3 m circa.

So because it's an equilateral triangle, you can cut the triangle in half and make a right triangle with a hypotenuse of 32. The bottom of the triangle would be half of 32, which is 16, because you cut the triangle in half. Now you can use the pythagorean theorem to solve for the height.
The answer is whatever b is:
b =
So your answer is 27.713.
The answer is whatever b is:
b =
So your answer is 27.713.
<h2>The Pythagorean Theorem</h2>
The Pythagorean Theorem:
- <em>a</em> and <em>b</em> are the two legs in a right triangle
- <em>c</em> is the hypotenuse (the longest side of a right triangle; opposite the 90° angle
- <em>*keep in mind that this theorem applies only to right triangles</em>
We're given:
- Legs = 9 units and 12 units
- Hypotenuse = <em>c</em>
