Set up a ratio:
4 gallons / 30 plants = X gallons / 45 plants
Cross multiply:
4 * 45 = 30 * x
180 = 30x
Divide both sides by 30:
x = 180 / 30
x = 6
It would take 6 gallons.

Step-by-step explanation:
So hmm notice the picture below
you have the center, and a point on the circle... all you need is the radius

then use that radius in the circle's equation
35. is c : square root of 64 is 8 and the square root of 8 can be simplifed to 4 x 2, square root of 4 is 2
36 is d : Denominator of the fraction represents what it is being rooted by and the numerator is what the regular number is squared by.
