Calculate the area in square meters of a circular skating rink that has a radius 11.2m. The relationship btwn the (A) and the radius (R) is A=
What's the problem here? A = pi*r^2
To calculate the area of a circle, you can use the formula A = π * R^2, where A represents the area and R represents the radius.
In this case, the radius of the circular skating rink is given as 11.2m. Now, let's substitute this value into the formula to find the area.
A = π * R^2
A = π * (11.2)^2
A = π * 125.44
The square of 11.2 is 125.44, and since π is approximately 3.14, we can calculate the area as:
A = 3.14 * 125.44
A ≈ 394.43 square meters
Therefore, the area of the circular skating rink is approximately 394.43 square meters.
