Given:
Circumference of a circle = C
Diameter of a circle = d
To find:
The relationship between the circumference, c, and diameter, d, of any circle.
Solution:
We know that, circumference of a circle is

It can be written as

![[\because d=2r]](https://tex.z-dn.net/?f=%5B%5Cbecause%20d%3D2r%5D)
On dividing both sides by d, we get

Therefore, the correct option is (F).
<em>3/4 is the total.</em>

Answer:
27.5cm^2
Step-by-step explanation:
you can cut the triangle to make two right triangles
so 11 is the height and the width is 2.5 since your cutting the triangle in half
so 11x2.5=27.5 since its a right triangle you have to divide by two 27.5/2=13.75
that's the answer for one of the triangles now multiply it by two since you need the two right triangle to make the other triangle so the answer is 27.5
