Question

PLEASE HELP i have been on this question forever

Answer 1

1520.5

Explanation:

The area of a circle is pi times r^2. r stands for radius. r, which is 22 squared is 484, Multiply that with pi and you have your answer.

Answer 2

The area of circle is 1520.5 in².

Step-by-step explanation:

DIAGRAM :

`\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\large{22\ in}}\end{picture}`

`\begin{gathered}\end{gathered}`

SOLUTION :

Here's the required formula to find the area of circle :

`\longrightarrow{\sf{A_((Circle)) = \pi{r}^(2)}}`

• A = Area
• π = 3.14
• r = radius

Substituting all the given values in the formula to find the area of circle :

`{:\implies{\tt{A_((Circle)) = \pi{r}^(2)}}}`

`{:\implies{\tt{A_((Circle)) = 3.14{(22)}^(2)}}}`

`{:\implies{\tt{A_((Circle)) = 3.14{(22 * 22)}}}}`

`{:\implies{\tt{A_((Circle)) = 3.14{(484)}}}}`

`{:\implies{\tt{A_((Circle)) = 3.14 * 484}}}`

`{:\implies{\tt{A_((Circle)) = 1520.53}}}`

`{:\implies{\tt{A_((Circle)) \approx 1520.5}}}`

`{\star{\boxed{\tt{A_((Circle)) \approx 1520.5 \: {in}^(2)}}}}`

Hence, the area of circle is 1520.5 in².

`\rule{300}{2.5}`
