Step-by-step explanation:

\underline{\underline{\maltese\: \: \textbf{\textsf{Question}}}}

  • A wire is in the form of a square with side 22cm. It is reshaped and bent into the form of circle. Calculate the area of the circle ?

\underline{\underline{\maltese\: \: \textbf{\textsf{Answer}}}}

  • After solving this question we will get the area of the circle as 616cm².

\underline{\underline{\maltese\: \: \textbf{\textsf{Given}}}}

  • Side of the square wire = 22cm.
  • It is reshaped and bent into the form of circle.

\underline{\underline{\maltese\: \: \textbf{\textsf{To\ Find}}}}

  • We have to find out the area of the circle.

\underline{\underline{\maltese\: \: \textbf{\textsf{Basic\ Terms}}}}

  • Circle : A circle is a round shaped figure that has no corners or edges.
  • Perimeter : Perimeter is the distance around a two-dimensional shape.
  • Area : The area can be defined as the space occupied by a flat shape or the surface of an object.
  • Radius : A line segment extending from the center of a circle or sphere to the circumference or bounding surface.

\underline{\underline{\maltese\: \: \textbf{\textsf{Solution}}}}

  • As we are given that there is a wire in the form of square with side 22cm. It is reshaped and bent into the form of circle.
  • As per the given information, we know that the wire is in the shape of a square.
  • So here, the first step to find the area of the circle is to find the perimeter of the square.
  • So, by using a required formula we will find out the perimeter of the square.

\underline{\underline{\maltese\: \: \textbf{\textsf{Calculations}}}}

We know that :-

 {\underline{\boxed{\sf {Perimeter\ of\ square\ =\ 4 \times side}}}}

Here,

  • Side = 22cm.

By applying the values, we get :-

 \sf \mapsto {Perimeter\ of\ square\ =\ 4 \times side}

 \sf \mapsto {Perimeter\ of\ square\ =\ 4 \times 22cm}

 \sf \mapsto {Perimeter\ of\ square\ =\ 88cm}

 {\therefore{\underline{\boxed{\tt {Perimeter\ of\ square\ =\ 88cm.}}}}}

  • Now, we have the perimeter of the square which is equal to the circumference of circle.
  • So, the second step in finding the area of the circle is to find out the radius of the circle.
  • So, by using a required formula we will find out the radius of the circle.

We know that :-

 {\underline{\boxed{\sf {Circumference\ of\ circle\ =\ 2{\pi}r}}}}

Here,

  • Circumference of circle = 88cm.
  • π = 22/7.

By applying the values, we get :-

 \sf \mapsto {Circumference\ of\ circle\ =\ 2{\pi}r}

 \sf \mapsto {88cm\ =\ 2 \times \dfrac{22}{7} \times r}

 \sf \mapsto {88cm\ =\ \dfrac{44}{7} \times r}

 \sf \mapsto {r\ =\ \dfrac{88 \times 7}{44}}

 \sf \mapsto {r\ =\ \dfrac{616}{44}}

 \sf \mapsto {r\ =\ 14cm}

 {\therefore{\underline{\boxed{\tt {Radius\ of\ the\ circle\ =\ 14cm.}}}}}

  • Now, we have the radius of the circle. So, the last step is to find the area of the circle.
  • So, by using a required formula we will find out the area of the circle.

We know that :-

 {\underline{\boxed{\sf {Area\ of\ circle\ =\ {\pi}r^2}}}}

Here,

  • π = 22/7.
  • r (radius) = 14cm.

By applying the values, we get :-

 \sf \mapsto {Area\ of\ circle\ =\ {\pi}r^2}

 \sf \mapsto {Area\ of\ circle\ =\ \dfrac{22}{7} \times 14^2}

 \sf \mapsto {Area\ of\ circle\ =\ \dfrac{22}{7} \times 14 \times 14}

 \sf \mapsto {Area\ of\ circle\ =\ 616cm^2}

 {\therefore{\underline{\boxed{\tt {Area\ of\ the\ circle\ =\ 616cm^2.}}}}}
