Answer:
530.66 cm²
Step-by-step explanation:
A formula for the area of the circular disc can be written as ...
A = C²/(4π)
A = (81.64²)/(4·3.14) = 6665.0896/12.56
A = 530.66 . . . . square centimeters
Answer:
If 9x is not =27, then x is not =3
Step-by-step explanation:
Going out on a limb here, please ignore if I'm missing it:
If 9x is not =27, then x is not =3
(I can't type the equal sign with a slash through it.)
Answer:

Step-by-step explanation:
Answer:
7√3
Step-by-step explanation:
We can use pythagoreans theorem to solve this
Since, we know one side, and the hypotenuse, we can solve for the other side.
Pythagoreans theorem: a²+b²=c²
Where a and b are two sides, and c is the hypotenuse (the side opposite of the right angle)
In this triangle, 7 is the side, and 14 is the hypotenuse.
I will plug in the values into pythagoreans theorem, and then simplify:
So x = 7√3
