Answer:
V = πr²h
To determine the volume of a cylinder you have to multiply the area of the base by the height of the cylinder.
Step-by-step explanation:
The base of a cylinder is a circle. So we must find the area of the circle first. (Which is πr²)
Then we multiply the height by the area of the circle.
V = π·r²·h
This can be used in different ways as well,
if we don't know the radius but know everything else we could use the formula:
(r = √(V/πh))
If we don't know the height we use this formula:
(h = V/(πr²))

Step-by-step explanation:
Suppose cities represented by C', suburbs represented by S and rural represented by R,
Let x be the total number of bonds issued throughout the US,
According to the question,
n(A) = 70% of x = 0.7x,
n(B) = 10% of x = 0.1x,
n(C) = 20% of x = 0.2x,
n(A∩C') = 50% of n(A) = 0.5 × 0.7x = 0.35x,
n(A∩S) = 20% of n(A) = 0.2 × 0.7x = 0.14x,
n(A∩R) = 30% of n(A) = 0.3 × 0.7x = 0.21x,
n(B∩C') = 40% of n(B) = 0.4 × 0.1x = 0.04x,
n(B∩S) = 30% of n(B) = 0.3 × 0.1x = 0.03x,
n(B∩R) = 30% of n(B) = 0.3 × 0.1x = 0.03x,
n(C∩C') = 60% of n(C) = 0.6 × 0.2x = 0.12x,
n(C∩S) = 15% of n(C) = 0.15 × 0.2x = 0.03x,
n(C∩R) = 25% of n(C) = 0.25 × 0.2x = 0.05x,
n(C') = n(A∩C') + n(B∩C') + n(C∩C') = 0.35x + 0.04x + 0.12x = 0.51x
n(S) = n(A∩S) + n(B∩S) + n(C∩S) = 0.14x + 0.03x + 0.03x = 0.20x

200 30-g flower pots can a 6-kg pack of soil fill up .
<u>Step-by-step explanation:</u>
Here we have ,
Weight of flower pot as :
⇒
Given there is a 6-kg pack of pack of soil , We need to find the number of flower pots we can have to fill up soil . Let's find out:
Let weight of pack of soil be :
⇒
⇒
⇒
Hence , the number of flower pots we can have is given by :
⇒
⇒
⇒
Therefore , 200 30-g flower pots can a 6-kg pack of soil fill up .
