Answer: The area is 9π unit squared ( in terms of π)
Step-by-step explanation:
From the equation for area of a circle, A = πr²
Where A is the area of the circle
r is the radius of the circle
From the question, the radius, r of the circle is 3
r = 3
Therefore, the Area of the circle is given by
A = π × (3)²
A = π×3×3
A = 9π unit squared ( in terms of π)
Hence, the area is 9π unit squared
OR
Since π is given as 3.14
Then,
A = 3.14 × (3)²
A = 3.14 × 3 × 3
A = 28.26 unit squared
Hence, Area is 28.26 unit squared (in decimal)
