Answer:
The diameter of the circle O is <em>12 units</em>
Step-by-step explanation:
There is no data in the image provided. To better help you, I'm assuming we have an arbitrary value of

and the triangle B0C is right
<u>Relations in the Circle</u>
The diameter (D) is twice the radius (r) and the radius is the distance measured from the center of the circle to any point of the circumference.
Since the triangle B0C has a right angle, BD is the hypotenuse and 0B=0C=r
Applying Pythagoras's theorem:

Thus we have




The diameter of the circle O is D=2(6) = 12 units
Answer:

Step-by-step explanation:
Given
The attached square
Required
Find BE
First, we calculate BD (the diagonal) using Pythagoras theorem.

Since the shape is a square, then

So:


Take square roots



BE is half BD.
So:



Answer: n minus c would equal c c minus b would equal z
Step-by-step explanation:
Answer: 98
Step-by-step explanation: 25+24+25+24
There are two parts to a rectangle. The opposite sides are the same. You add them all up to equal 98.
Hope this helps and would appreciate getting brainliest to level up :)
