Volume of a cylinder = pi r^2 h where r = radius of the base and h = the height.
so if we are given a radius of 2 cm and a volume of 180 cm^3 we work out the height as follows:-
180 = pi * 2^2 * h
h = 180 / (pi*2^2)
height h = 180 / 4pi = 14.32 cm to nearest hundredth
Answer:
x > ![\frac{14}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B14%7D%7B5%7D)
Step-by-step explanation:
Given
> 7 ( multiply both sides by 2 to clear the fraction )
5x > 14 ( divide both sides by 5 )
x > ![\frac{14}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B14%7D%7B5%7D)

Answer:
A) 1 < x < ∞
Step-by-step explanation:
"Increasing" means the graph goes up to the right. This graph is increasing for values of x greater than 1. (x=1 is a minimum. The graph is decreasing toward the minimum on the left of that value, and increasing from the minimum on the right of that value.)
1 < x < ∞
Answer:
0.0003456
Step-by-step explanation:
.456 x 10^-4 = 3.456 x .0001 = 0.0003456
tell me if i did it right because i dont think i did.
Answer:
The answer to your question is the letter B.
Step-by-step explanation:
Data
Point = (-2, 10)
Center = (-2, 6)
Process
1.- Find the radius using the distance between two points
dCP = ![\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x2%20-%20x1%29%5E%7B2%7D%2B%20%28y2%20-%20y1%29%5E%7B2%7D%7D)
-Substitution
dCP = ![\sqrt{(-2 + 2)^{2}+ (6 - 10)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-2%20%2B%202%29%5E%7B2%7D%2B%20%286%20-%2010%29%5E%7B2%7D%7D)
dCP = ![\sqrt{(0)^{2}+ (-4)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%280%29%5E%7B2%7D%2B%20%28-4%29%5E%7B2%7D%7D)
dCP = ![\sqrt{16}](https://tex.z-dn.net/?f=%5Csqrt%7B16%7D)
dCP = 4
2.- Write the equation of the circle
Standard equation (x - h)² + (y - k)² = r²
h = -2
k = 6
r = 4
(x + 2)² + (y - 6)² = 4²
Equation (x + 2)² + (y - 6)² = 16
