V = volume
R = radius
H = height
² = squared
radius = 10 cm
Height = 8 cm
V = π10²×8
V ≈ 3.14 * 100*8
V ≈ 2512
r = 10cm, h = 8 cm.
Volume = π*10²*8 = π*100*8 = 800π
Volume = 800π cm³ or ≈ 800*3.142 ≈ 2513.6
Volume ≈ 2513.6 cm³

Usingthe percent rule, It is found that 6 is 12.5 percent of 48.
How to find how much percent 'a' is of 'b'?
Suppose a number is 'a' Suppose another number is 'b' We want to know how much percent of 'b' is 'a'. Then, it is calculated as:
(in percentage)
We are asked to find that 6 is what percent of 48.
Let x is the unknown percent.
100% / x% = 48/6
Now multiply both sides of the equation by x
(100/x)x = (48/6)x
Then divide both sides of the equation by (8) to get x
100 = 8x
100/8 = x
12.5 = x
x=12.5
Hence, It is found that 6 is 12.5 percent of 48.

100%/x%=48/6
(100/x)*x=(48/6)*x - we multiply both sides of the equation by x
100=8*x - we divide both sides of the equation by (8) to get x
100/8=x
12.5=x
x=12.5

The solution of the equation is x < 15/2.
What is an equation?
An equation is an expression that show the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between.
One solution was found as
x < 15/2
The equation by subtracting to the right of the greater than a sign from both sides of the inequality :

Answer:
Volume of Mixture A =90 ml
Volume of Mixture B =30 ml
Step-by-step explanation:
Let say, Mixture A + Mixture B = Mixture C
Volume of Mixture A is x
Volume of Mixture B is y
So, Volume of Mixture C is x+y = 120 ml
Now, Acid contain in Mixture A is 20% =0.2x
Acid contain in Mixture B is 80% =0.8y
Also, Acid contain in Mixture C is 35% =(0.35)(x+y) = 0.35×120=42
Now, we know that,
Acid contain of Mixture A + Acid contain of Mixture B=Acid contain of Mixture C
∴ 0.2x+0.8y=42
∴ 2x+8y=420
We get two linear equations
2x+8y=420 and x+y = 120
Solving above equation...
∴ x=120-y
Replacing x value in 2x+8y=420
∴ 2(120-y)+8y=420
∴ 240-2y+8y=420
∴ 6y=180
∴ y=30
Replacing y value in any equation
∴ x=120-y=120-30=90
∴ x=90
Thus,
Volume of Mixture A is x=90 ml
Volume of Mixture B is y=30 ml
