Use the illustration below to calculate the circumference of the circle. Assume that the marked point is the center of the circle, and that the three vertices of the triangle are on the circle

Answer 1

The circumference of your circle would be 3.14

Answer 2

first, you would use the pythagorean theorum to figure out hthe diameter of the circle

Answer 3

the diameter is 1, and 1 multiplied by pi (3.14) is equal to an area of 3.14. THat is the answer

Answer 4

Do you understand?

Answer 5

so 3.14 is the answer? o.O

Answer 6

0.8^2 + 0.6^2 = diameter

Answer 7

right

Answer 8

so you wouldn't have to do anything else?

Answer 9

well and of course, the circumference is always approximated. And no, you would not get anything else.

Answer 10

okay so how could I write it out? 0.8^ = 0.6^2 = 1 * pi would give you 3.14 because your using the Pythagorean theorem ?

Answer 11

first you right out 0.8^2 +0.6^2=c
0.64+0.36=1
then you use the one to solve for circumference
1*3.14 = a circumference of approx. 3.14

Answer 12

okay thank you so much!! (: I got it

Answer 13

im glad you understand!
