1 foot is 12 inches. 2 feet is 24 inches. yea so I'd say 30 inches is definitely longer
Answer:
Volume is 
Solution:
As per the question:
Diameter, d = 40 m
Radius, r = 20 m
Now,
From north to south, we consider this vertical distance as 'y' and height, h varies linearly as a function of y:
iff
h(y) = cy + d
Then
when y = 1 m
h(- 20) = 1 m
1 = c.(- 20) + d = - 20c + d (1)
when y = 9 m
h(20) = 9 m
9 = c.20 + d = 20c + d (2)
Adding eqn (1) and (2)
d = 5 m
Using d = 5 in eqn (2), we get:

Therefore,

Now, the Volume of the pool is given by:

where
A = 

Thus




![V = [- 533.33cos\theta + 1000\theta]_{0}^{2\pi}](https://tex.z-dn.net/?f=V%20%3D%20%5B-%20533.33cos%5Ctheta%20%2B%201000%5Ctheta%5D_%7B0%7D%5E%7B2%5Cpi%7D)

Answer:
Since 7 and 11 are both rational the sum and the difference are rational .
Step-by-step explanation:
Answer:
The factors are;
23, -23 , a , b
Step-by-step explanation:
Here, we want to write the factors of the given expression
-23 ab^2
The factors are simply those values or expression that can be divided by the given expressions
We have the factors as follows;
23
-23
a
b
Answer:
=1
=−7
Step-by-step explanation:
(+3)2−5=11
(+3)(+3)−5=11
2+3+3+9−5=11
2+6+9−5=11
x-1=0
x+7=0
