Question

The circumference of a circular park is 352 m. Find the area of the park.​

Answer 1

Answer:

A=πr²

C=2πr

A=

$\frac{c^{2} }{4\pi}$

=

$\frac{352 ^{2} }{4\pi}$

9859.96703m²

Answer 2

• We have to evaluate the above expression by using the given data.

            Given data:- Circumference of a circle is $352\ m.$

            To find:- Area of the park.

            Solution:-

           Circumference of circle$=2\pi r.$

                 $\begin{array}{l}352=2 \times \frac{22}{7} \times r \\352=\frac{44 r}{7} \\r=\frac{352 \times 7}{44} \\r=56 \mathrm{~m}\end{array}$

            The Area of the circle is $\pi r^{2}$

                $\text { Area }=\frac{22}{7} \times 56 \times 56\\\text { Area }=22 \times 8 \times 56\\\therefore \text { Area }=9856 \mathrm{~cm}^{2}.$

           Hence we will get the area of a park is $9856 \mathrm{~cm}^{2}.$
