Answer:
The area of the circle is equal 28.3 cm² to the nearest tenth.
Step-by-step explanation:
To find the area of the circle that has a radius of 3, we will simply use the formula;
Area of a cirle = π r²
where π is a constand and r is the radius.
From the question given π = 3.14 and r=3
We can now proceed to insert the value into the formula;
Area of a cirle = π r²
=3.14×3²
=3.14×9
=28.26
≈28.3 cm²
Therefore, the area of the circle is equal 28.3 cm² to the nearest tenth.
