Question

Ruby is visiting a wildlife center to gather information for her term paper. The center has a circular pond with a diameter of 20 meters. What is the approximate area of the pond?

Answer 1

Since, the diameter of the circular pond = 20 meter,

⇒ Radius of the pond = 20/2 = 10 meter.

Thus, the area of the pond,

A=π×(10)^2

$\frac{22}{7} \times 100$

$\frac{2200}{7}$

$= 314 square \: meter$

Hence, The approximate area of the given circular pond is 314 square meter.

hope it helps you

Answer 2

Answer:

Step-by-step explanation:

          d = 20 metees

       r = d/2

    therefore

         r=20/2

        r=10 metres

   Area of circular pond = $\pi$$r^{2}$

                                          = 22/7 x 100

                                          = 2200/7

                                         =  314.2 $m^{2}$
