square meters
The area of a circle is given by the formula A = πr^2, where A is the area and r is the radius.
Using the given radius of 2.5 m, we can calculate the area as follows:
A = π * (2.5)^2
= π * 6.25
≈ 19.63
Rounding to the nearest tenth, the area of the circle is approximately 19.6 square meters.
To find the area of a circle, you can use the formula A = πr², where A represents the area and r represents the radius.
In this case, the radius is given as 2.5 m. So, substituting the value of the radius into the formula, we have:
A = π(2.5)²
To approximate the value of π, we can use 3.14 (rounded to two decimal places).
A = 3.14(2.5)²
Calculating the square of 2.5, we have:
A = 3.14(6.25)
Multiplying the values:
A = 19.625
Rounding the answer to the nearest tenth, the area of the circle with a radius of 2.5 m is approximately 19.6 square meters.
To find the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius of the circle.
In this case, the radius is given as 2.5 m.
Plug in the value of the radius into the formula:
A = π(2.5)^2
Simplify the expression:
A = π * 6.25
Now, you need to evaluate the expression using an approximation for π. Let's round π to the nearest hundredth, which is 3.14:
A ≈ 3.14 * 6.25
A ≈ 19.625
Finally, round the value to the nearest tenth:
A ≈ 19.6 square meters
