Answer:
Step-by-step explanation:
Hello!
Expand the square using the Distributive Property.
<h3>Expand</h3>Distributive x - 5 to each factor
The answer is .
We can also use a special binomial product formula.
Formula:
We get the same answer both ways.
Given
Your family has a circular swimming pool.
The radius of the pool is 9 feet and and its depth is 4 feet.
Find out the volume of the pool.
To proof
As depth is given in the question that means the shape of the swimming pool
is cylinder.
Formula
where r = radius
h = height
now
radius of the pool is 9 feet and and its depth is 4 feet.
put all the values in the above equation
we get
use 3.14 to approximate pi
we get
= 1017.4 ( approx )feet²
Hence proved
