Answer: False

Step-by-step explanation:

Inscribing a circle in a triangle means that the circle touches the 3 sides of the triangle.

The center of the circle must be placed at the incenter of the triangle, you can find this point by bisecting two with a compas, the point where the lines intersect is the incenter.

This point does not necesarly coincides with the center of the triangle, so the statement is false.

Student to faculty is 17:3 The total is 740 how many students and faculty are at the college
inn [45]
Let the faculties be X and the number of students be Y.
X/Y = 17/3
3X= 17Y
X=17Y/3
Let that be equation 1
We also know that X+Y = 740. Let it be equation 2
Substitute equation 1 in equation 2
(17Y/3)+Y=  740
20Y/3 = 740
Y=111
Since the total is 740, then X equal 740-111 =629.
The number of faculties is 111 and the number of students is 629.

melomori [17]

The length of the radius will be 22 units.

<h3>What is the radius?</h3>

The radius of a circle is defined as the distance of the center of the circle to its outer layer. It is a locus of a point present at some distance from the center point.

Now from the question, we have an expression:

r=(\dfrac{6}{85} )\times(\dfrac{85}{12} )\times (\dfrac{121}{36} )\times (\dfrac{157}{12} )

By solving the above equation we get

r=(\dfrac{18997}{864} )

r=22

Hence the length of the radius will be 22 units.
