The value of x should be 1 because since there's no number front of the x....so you always have to pretend that there's a invisible 1.
This equals one and one eighth
Answer:
2 * (Area/pi)^(1/2) = diameter
Step-by-step explanation:
The equation for the area of a circle is A = pi * r^2
We can divide both sides by pi to get:
A/pi = r^2
Then take the square root of both sides to get:
(A/pi)^(1/2) = r
Then, since D = 2 * r, we can multiply both sides of the above equation by 2 to get:
2 * (A/pi)^(1/2) = 2 * r = D
Answer:
25% is the answer because 25 x 4 = 100% and 20x4= 80
