Answer: Ok So If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14.
The formula for working out the circumference of a circle is:
Circumference of circle = π x Diameter of circle
This is typically written as C = πd. This tells us that the circumference of the circle is three “and a bit” times as long as the diameter."
Step-by-step explanation:
Here, Cotton fabric = 2 yards
yards of fleece fabric = 2 1/2 yards
Total fabric = 2 + 2 1/2 = 4 1/2
In short, Your Answer would be: Option C
Hope this helps!
I thinks the answer is 90 because the figure has. No sides and has an even number of triangles around it
