PLEASE HELP i have been on this question forever

Answer 1

Answer:

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 :

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

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

${:\implies{\tt{A_{(Circle)} = 3.14{(22 \times 22)}}}}$

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

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

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

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

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

Hence, the area of circle is 1520.5 in².

$\rule{300}{2.5}$

Answer 2

Answer:

1520.5

Step-by-step 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.
