Answer:
424.1175
Step-by-step explanation:
Volume of the total pool = π[tex]r^{2}[/tex]h
= π x [tex]6^{2}[/tex] x 5
= 565.49
needed to fill a 3/4 of the pool = [tex]\frac{3}{4}[/tex] x 565.49
= 424.1175
Considering the volume of a cylinder, the amount of water needed to fill a 3/4 of the pool is 135π ft³.
Definition of volumeVolume is a measure of the space occupied by an object in three-dimensional space, using cubic units to measure it. The volume formula depends on the shape of the figure and its different dimensions.
Volume can be considered as the capacity of a container to hold a quantity of fluid (gas or liquid).
Volume of a cylinderIn the case of a cylinder, it is characterized by having two circular bases and a surface that joins the two bases. So the volume of a cylinder is π×r²×h.
Amount of water neededIn first place, you must know that the length of the radius is half the length of the diameter.
On the other side, it is needed to fill a 3/4 of the pool.
Then, considering the definition of volume and the expression of volume of a cylinder, the amount of water needed is calculated as:
amount of water=(3/4)×π×(12 ft ÷2)²× 5 ft
Solving:
amount of water=(3/4)×π×(6 ft)²× 5 ft
amount of water= 135π ft³
Finally, the amount of water needed to fill a 3/4 of the pool is 135π ft³.

Dina and Masha start cycling on a 20 km bike path at the same time. When Dina reaches the end of the path, Masha still has 4 km of the path left to cycle. If Dina’s cycling speed is 10 km/h, how much time longer will Masha need to complete the path?
I WILL AWARD BRAINLIEST
Answer: Masha needs 40 more minutes to complete the path.
Step-by-step explanation:
So if Dina is cycling speed is 10km per hour that means it will take Dina 2 hours to completed the the path.
Here; [tex]\frac{10km}{1h}[/tex] = [tex]\frac{20km}{x }[/tex]
10x = 20
x= 2
But since Masha still have 4 more km to go you will add 20 + 4 =24
[tex]\frac{10}{1}[/tex] = [tex]\frac{24}{x}[/tex]
10x= 24
x= 2.4

a) Exterior Angle Theorem. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle.
The figure is made up of 2 cones and a cylinder. The cones and cylinder have a 4 cm diameter.
What is the exact volume of this figure?
Answer:
62.84
Step-by-step explanation:
Volume of both cones is approximately 12.57
formula= pi*r^2*h/3
Volume of the cylinder is approximately 37.7
formula= pi*r^2*h
you add the volumes
12.57+12.57+37.7
= 62.84

Gunther drew a circle. The radius of the circle is 20 inches. He uses the formula below to determine the area of his circle
Answer:
D.) 400π
Step-by-step explanation:
The formula for the area of a circle is:
A = πr²
Substitute the radius into the equation:
A = πr²
A = π(20²)
Solve:
A = π(20²)
A = 400π
Therefore, the area of the circle is 400π square inches.

Using first principle, find the slope of a tangent line to the curve f(x) = x^2 - 3x +5 at x=3
Answer:
y=3x−4
Step-by-step explanation:
find the tangent line to f(x)=x2−3x+5 at x=3
First, find the value of the function at the given point: y0=f(3)=5
Second, find the slope of the tangent line, which is the derivative of the function, evaluated at the point: m=f′(3)
Find the derivative: f′(x)=2x−3
Next, we evaluate the derivative at the given point to find the slope.
m=f′(3)=3
Finally, the equation of the tangent line is y−y0=m(x−x0)
Plug the values that we found, we get that y−(5)=3(x−(3))
So basically: y=3x−4

Given the expression [tex]3*5*5*5*5*5*5[/tex]
In order to get the equivalent expression, first we must note the repetition of the value 5. Since the value of 5 is repeated 6 times during the multiplication, it can be written in indicinal form as shown;
[tex]3*5^{6}[/tex]
[tex]5^{6}[/tex] in the equation means that 5 is being repeated 6 times.

Julie and Ryan want to refinish the gym floor at the community center. The rectangular floor is 15.2 meters wide and 25.6 meters long. If each gallon of polyurethane covers about 180 square meters, how many gallons should they buy?
Answer:
3 gallons
Step-by-step explanation:
We need to find the area of the floor first:
25.6*15.2=389.12
Now we divide the surface area by gallons of polyurethane.
389.12÷180=2.161777777777777777777777777777....≈2.16 gallons needed. But OH WAIT! You can't buy 0.16 of a gallon so you need 3 gallons.

32° 15' 66" is the same as
Round to the nearest hundredth of a degree.
The 32° 15' 66" is the same as 32.27 degree because 1 degree = 60 minutes = 3600 seconds.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.
We have:
32° 15' 66"
Here 15' represents the minute and 66" represents the seconds.
We know 1 degree = 60 minutes = 3600 seconds
15' in degree = 0.25 degree
66" in degree = 0.01833 degree
= 32 + 0.25 + 0.01833
= 32.268 ≈ 32.27 degree
Thus, the 32° 15' 66" is the same as 32.27 degree because 1 degree = 60 minutes = 3600 seconds.
