The diameter is 6. Explanation:
radius: 3.14r^2
28.26=3.14r^2
28.26/3.14=r^2
r^2=9
r=3
and we know that diameter is two times the radius so:
3*2=6
diameter equals 6.
if you want to check it plug back in:
3^2 * 3.14 = 28.26
hope this helped :)
One is -10,and second is 30.
There are many different ways to figure this out but may I ask you one question....do you know whether the two legs are congruent or just the right angle?
