Final answer:

The radius of a circle with an area of 19 m² is approximately 2.46 meters, calculated using the area formula for a circle and taking the square root of the result rounded to two decimal places.

Step-by-step explanation:

To calculate the radius of a circle with an area of 19 m², we can use the formula for the area of a circle, which is A = πr². Substituting the given area we have 19 = πr². To solve for the radius, r, we first divide both sides by π:

r² = 19 ÷ π

Using the value of π as approximately 3.14159, we carry out the division to get:

r² = 19 ÷ 3.14159

r² ≈ 6.0455

Then we take the square root of both sides to find the radius:

r ≈ √6.0455

r ≈ 2.46 m

Therefore, the radius of a circle with an area of 19 m², rounded to two decimals, is approximately 2.46 meters.
