The volume of a cylinder can be found with the following equation
[tex]V = r^2h\pi[/tex]
After inputting the known information we get
[tex]980\pi = r^220\pi \\\\[/tex]
Which simplifies to
radius = 7 or (-7)
For proof's sake, we can try the equation again with the known radius
[tex]980\pi = r^220\pi \\980\pi = (7^2)20\pi \\980\pi = (49)20\pi \\980\pi = 980\pi \\[/tex]
And because the radius is being squared, it can either be negative or positive.

The volume of water needed to fill the pool is 180π square feet.
What is a cylinder?It is a three-dimensional shape with two parallel circular bases and a curve surface.
Volume = π r² h
r = radius of the cylinder
h = height of the cylinder
We have,
Diameter of the cylinder = 12 ft
Radius = diameter/2 = 12/2 = 6 ft
Height of the cylinder = 5 ft
The volume of the cylinder:
= πr²h
= π x 6² x 5
= π x 36 x 5
= 180π square feet
Thus,
The volume of water needed to fill the pool is 180π square feet.

Consider this equation.
sin(θ)= 3sqrt10/10
If θ is an angle in quadrant II, what is the value of tan(θ) ?
Answers
Answer:
tan x = -3 (Answer A)
Step-by-step explanation:
We want to find the tangent of this angle "theta," and recall the trig identity
(sin x)^2 + (cos x)^2 = 1.
3√10
If sin x = -----------
10
90
then (sin x)^2 = ----------- = 9/10
100
and (cos x)^2 = 1 - 9/10 = 1/10
sin x 3√10/10
Then tan x = ---------- = -------------- = -3 (Answer A)
cos x 1√10/10
The tangent function is negative in Quadrant II. In Quadrant I tan x = +3
Answer:
A
Step-by-step explanation:
Using the trig identity
sin²x + cos²x = 1 , then cos x = ± [tex]\sqrt{1-(\frac{3\sqrt{10} }{10})^2 }[/tex]
Given
sinθ = [tex]\frac{3\sqrt{10} }{10}[/tex] , then
cosθ = ± [tex]\sqrt{1-(\frac{3\sqrt{10} }{10})^2 }[/tex]
= ± [tex]\sqrt{1-\frac{9}{10} }[/tex]
= ± [tex]\sqrt{\frac{1}{10} }[/tex]
Since θ is in second quadrant where cosθ < 0 , then
cosθ = - [tex]\frac{1}{\sqrt{10} }[/tex]
Then
tanθ = [tex]\frac{sin0}{cos0}[/tex] = [tex]\frac{\frac{3\sqrt{10} }{10} }{\frac{-1}{\sqrt{10} } }[/tex] = - 3 → A

Twenty pounds of beans are distributed equally into 16 bags to give out at the food bank. How many pounds of beans are in each bag? Enter your answer in the simplest form. There are pounds of beans in each bag.
Answers
Answer: 1¼ pounds
Step-by-step explanation:
Since 20 pounds of beans are distributed equally into 16 bags to give out at the food bank, the amount of pounds of beans that are in each bag will be gotten by dividing 20 by 16 which will be:
= 20 pounds / 16
= 1¼ pounds
Therefore, there are 1¼ pounds of beans in each bag.
