Answer:
The area of circle is 1520.5 in².
Step-by-step explanation:
DIAGRAM :
[tex]\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}[/tex]
[tex]\begin{gathered}\end{gathered}[/tex]
SOLUTION :
Here's the required formula to find the area of circle :
[tex]\longrightarrow{\sf{A_{(Circle)} = \pi{r}^{2}}}[/tex]
- A = Area
- π = 3.14
- r = radius
Substituting all the given values in the formula to find the area of circle :
[tex]{:\implies{\tt{A_{(Circle)} = \pi{r}^{2}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(22)}^{2}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(22 \times 22)}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(484)}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14 \times 484}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 1520.53}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} \approx 1520.5}}}[/tex]
[tex]{\star{\boxed{\tt{A_{(Circle)} \approx 1520.5 \: {in}^{2}}}}}[/tex]
Hence, the area of circle is 1520.5 in².
