The binomial expansion: 
a = 2y, b = 4 x^3, n = 4
( x )^3k = x^ 9
k = 3
Answer: the coefficient is 512.

If the area of a circular pool is 300 square yards, what is its radius?
1 answer:
Answer:
<h2>radius = 9.77 yards</h2>Step-by-step explanation:
Since the pool is circular
Area of a circle = πr²
where
r is the radius
From the question
Area = 300 square yards
To find the radius substitute the value of the area into the above formula and solve for the radius
That's
300 = πr²
Divide both sides by π
We have
Find the square root of both sides
That's
r = 9.7720502
We have the final answer as
<h3>radius = 9.77 yards</h3>Hope this helps you
