Answer 1

@adillie do you know Pythagorean theorem?????

Answer 2

Yes, A^2+B^2=C^2

Answer 3

that would give me 1.36 for C

Answer 4

No
hypotenuse is the longest side opposite to the 90 degree angle
hypotenuse here is also diameter of the circle
once you have the diameter, you can find the radius and then the circumference

Answer 5

diameter is less than 1.36, you miscalculated or something

automatically i can see it's a 3-4-5 triangle or 6-8-10 or in this case
.6-.8-1.0

Answer 6

Wait so the C in the theorem isn't 1.36 I did .6 squared + .8 squared = 1 squared so then i square rooted 1

Answer 7

square root of 1 is 1 !

Answer 8

oh so the answer is 3.14?

Answer 9

No
What's circumference formula?

Answer 10

2*r*pi?

Answer 11

yeah, it's pi
you're right
