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

314 meters because the equation for the area of a circle is A = pi r squared

Answer 2

Area of pond = 314 meter².

Explanation:

Given : The center has a circular pond with a diameter of 20 meters.

To find : What is the approximate area of the pond.

Solution: We have given diameter = 20 meters.

Radius =
`(Diameter)/(2)`.

Radius =
`(20)/(2)`.

Radius = 10 meter .

Area of circular pond = pi ( radius) ².

Area of pond = 3.14 (10) ².

Area of pond = 3.14 * 100.

Area of pond = 314 meter².

Therefore, Area of pond = 314 meter².
