If the area of a circular pool is 300 square yards, what is its radius?
elixir [45]

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

{r}^{2}  =  \frac{300}{\pi}

Find the square root of both sides

That's

r =  \sqrt{ \frac{300}{\pi} }

r = 9.7720502

We have the final answer as

<h3>radius = 9.77 yards</h3>

Hope this helps you

Please help, im confused
elixir [45]
It look like that. 
Diameter = 2 so the radius = 1/2 * diameter = 1in

Volume of the cylinder =  pi r^2 h 

where h = height of the cylinder = 9 in

so volume = pi * 1^2 * 9  =  28.27 in^2  to nearest hundredth
