The radius of a circle is 3 cm. Find its area to the nearest tenth.
To find the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius of the circle. Given that the radius is 3 cm, plug this value into the formula:
A = π(3)^2
A = π(9)
A ≈ 28.3 cm^2
Therefore, the area of the circle is approximately 28.3 cm^2.
