Answer:
100 pi (314.16)
Step-by-step explanation:
Because the diameter is 20 in, that makes the radius = 20/2 inches = 10 inches.
10^2 * pi = area
100 pi = area
314.16 is approx. area.
Answer:
x = ![\frac{A}{4y}](https://tex.z-dn.net/?f=%5Cfrac%7BA%7D%7B4y%7D)
Step-by-step explanation:
Given
A = 4xy ( isolate x by dividing both sides by 4y )
= x
Answer:
Step-by-step explanation:
Subtract 4x from both sides
4x-4x + 2y = -4x - 12
2y = - 4x - 12
Divide by 2
2y/2 = -4x/2 - 12/2
y = -2x - 6
The y intercept happens when x = 0
y intercept is - 6
or 0,-6
