An equilateral triangle with sides of length 6 is inscribed in a circle. what is the diameter of the circle?
a. 5.2
b. 6
c. 6.9
d. 7.5

c.6.9 units (to the nearest tenth of a unit)

Step-by-step explanation:

sin60=(s/2)/(d/2)  where s=side of triangle and d=diameter of circle

sin60=s/d

√(3/4)=s/d

d=s/√(3/4)

d=s√(4/3)

d=2s/√3 and since s=6

d=12/√3

d=√48

d≈6.9282

hope this helps:)sorry if it doesnt

6.9

Step-by-step explanation:i just took the test and got a hundred

what is all that apply?

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
