The radius of a circle is 3 m. Find its area to the nearest tenth.

28.3 square meters.

Step-by-step explanation:

So we know that the radius of the circle is 3 meters. With that, we can figure out the area of the circle.

The area of a circle is given by the formula:

Plug in 3 for r:

Square the number:

Use a calculator. Approximate:

Therefore, the area of the circle is approximately 28.3 square meters.

28.3 m²

Step-by-step explanation:

The area of a circle can be found using the following formula.

We know the radius of the circle is 3 meters. We can substitute 3 m in for the variable, r.

Evaluate the exponent.

(3m)² = 3m * 3m= 9 m²

Multiply pi and 9 meters squared.

9 m² * π = 28.2743339 m²

Round to the nearest tenth. The 7 in the hundredth place tells us to round the 2 in the tenth place to an 3

.

The area is approximately 28.3 square meters.
