Mathematics

Answer:

<h2>Y = 22.56 cm </h2>

Step-by-step explanation:

To find the diameter Y of the circle we must first find the radius of the circle

Area of a circle = πr²

where

r is the radius

From the question

Area = 400cm²

Substitute the value into the above formula and solve for the radius

That's

400 = πr²

Divide both sides by π

We have

{r}^{2}  =  \frac{400}{\pi}

Find the square root of both sides

r =  \sqrt{  \frac{400}{\pi}  }

radius = 11.28 cm

Since we have the radius we can use it to find the diameter Y using the formula

diameter = radius × 2

radius = 11.28

Y = 11. 28 × 2

We have the final answer as

<h3>Y = 22.56 cm</h3>

Hope this helps you
