Final Answer:

The area of the circle, approximating π as 3.14 and rounding to the nearest tenth, is A = 28.3 square units.

Step-by-step explanation:

To find the area of a circle, we use the formulaA = πr^2 , where r is the radius. In this case, we approximate π as 3.14. Let's assume the radius of the circle is given as r units.

Substitute the value of π into the formula:


A=3.14×r 2

Now, if we were given a specific radius, say r = 3 ) units, we would plug that value in and calculate the area. However, since the question doesn't provide a specific radius, the answer is expressed in terms of r . When rounding to the nearest tenth, the final answer becomes A = 28.3 square units.

This means that for any circle with an unspecified radius, its area would be 28.3 square units when using the approximation π approx 3.14. It's important to note that this is an approximation and the actual area may vary based on the precise value of π and the specific radius of the circle. The use of 3.14 is a common practice for quick estimations in practical scenarios where a more accurate value is not required.
