Find the area of a circular pond whose radius is 31 meters. (Use π = 3.14 as an approximate value.)
The area of a circular pond with a radius of 31 meters is approximately 3022.14 square meters.
wrong again!
To find the area of a circular pond, you can use the formula: A = πr^2, where A is the area and r is the radius.
Given that the radius of the pond is 31 meters and π is approximately 3.14, we can substitute these values into the formula to find the area:
A = 3.14 * (31)^2
Simplifying this equation:
A = 3.14 * 961
A = 3019.54
Therefore, the area of the circular pond with a radius of 31 meters is approximately 3019.54 square meters.
To find the area of a circular pond, we can use the formula for the area of a circle:
Area = π * radius^2
Given that the radius of the pond is 31 meters, we can substitute this value into the formula:
Area = 3.14 * 31^2
Now, let's calculate:
Area = 3.14 * 961
Area ≈ 3015.94 square meters
Therefore, the area of the circular pond, with a radius of 31 meters, is approximately 3015.94 square meters.
