Question

Hi i need answer to this question if you could help me find the answer?

Answer 1

78.5 cuz 5x5 is 25 and 25 x 3.14 is 78.5

Step-by-step explanation:

Answer 2

Given:

There are given that the radius of the swimming pool is 5 meters.

Step-by-step explanation:

According to the question:

We need to find the area for the swimming pool.

So,

To find the area of the swimming pool, we need to use the area of a circle formula.

So,

From the formula of the area of the circle:

`A=\pi r^2`

Then,

Put the value of r into the given formula:

So,

`\begin{gathered} A=\pi r^(2) \\ A=(3.14)(5)^2 \end{gathered}`

Then,

`\begin{gathered} A=(3.14)(5)^(2) \\ A=(3.14)25 \\ A=78.5m^2 \end{gathered}`

Final answer:

Hence, the value of the area of a swimming pool is shown below:

`A=78.5m^(2)`
