The diameter of the pond is 38 m.
The radius of the pond is 19 m.
The area of the pond is 361 m^2.
Step-by-step explanation:
We know that the circumference C of a circle is equal to
![C=\pi D](/tpl/images/0590/5855/1ba98.png)
In this case, C is equal to 120 m.
The diameter is then:
![D=C/\pi=120/3.14=38.21\approx 38](/tpl/images/0590/5855/03ce4.png)
Rounded to the nearest whole number, the diameter is D=38 metres.
The radius is equal to half the diameter, so the radius of this pond is R=19 metres.

The area can be calculated from the radius as:
![A=r^2=19^2=361](/tpl/images/0590/5855/75e10.png)
The area is 361 m^2
