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:
x = - 
Step-by-step explanation:
Given a quadratic equation in standard form , that is
y = ax² + bx + c = 0 ; a ≠ 0
Then the x- coordinate of the vertex is
= - 
x² + bx + c = 0 ← is in standard form
with a = 1, b = b, thus
= -
In order to find the volume of the tank, you just need to use this formula :
V = π r^2 h
r = 101.5 ft (half the diameter)
h = 25 ft
V = π (101.5)^2 x 25
= 809462.5 ft^3
