Answer:
The answer is
<h2>r =4 ft</h2>
Step-by-step explanation:
Area of a circle is given by πr²
Where r is the radius
From the question
Area = 64 ft²
So the radius is
64 = πr²
Divide both sides by π

Find the square root of both sides

r = 4 ft

Answer:
Step-by-step explanation:
Answer:
A) The height of the water increases 2 inches per minute.
Step-by-step explanation:
Slope is the rate of change of height
m = (16 - 12)/(4 - 2) = 4/2 = 2
2 inch per min
Positive slope implies increase
Since both objects are assumed to have the same volume, matching the formulas we'll get:
π

h =

π

h
Having both <span>π and h at both sides of the equation, we can ignore them, so:
</span><span>

=


</span>
And clearing R, according to the equation rules, we'll get:
= R
