Answer:
d = 10
Step-by-step explanation:
A = πr²
81 /π = r²
r² ≈ 25
r = 5
d = 5(2) or 10
I think the answer would be inductive! I hope this helps!
Answer:
Step-by-step explanation:
4√6 X 2√2 4√3 16√3 32√3 8√12
I believe the answer is 11.24 units.
If you are given an isosceles triangle with a vertex angle of 38 degrees, that would tell you that the other angles in the triangle are both 71 degrees.
In this case, I would use ratios of an angle to it's opposite side. Therefore, we would have: (38°)/X = (71°)/(21 units)
Now you can solve for X, algebraically, and the answer I got was 11.24 units.
