The diameter of a circle is 6 cm. Find its area to the nearest tenth
To find the area of a circle, you use the formula A = πr^2, where A is the area and r is the radius of the circle.
Since the diameter is given, we first need to find the radius by dividing the diameter by 2:
r = 6 cm / 2 = 3 cm
Now we can plug the radius into the formula to find the area:
A = π(3 cm)^2
A = π(9 cm^2)
A ≈ 28.3 cm^2
Therefore, the area of the circle to the nearest tenth is approximately 28.3 cm^2.
