What is the area of an 0.8 cm circle?

Answer 1

If 0.8cm is the radius (distance from the centre to the edge of the circle) of the circle, the area of the circle is 2.010619298 cm squared.

If 0.8cm is the diameter (distance from one side of the circle to the other), the circle's area is 0.5026548246cm squared.

Answer 2

The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. In this case, the radius is half of the diameter, which is 0.8 cm. Therefore, the radius is 0.4 cm. Plugging this value into the formula, we get A = π(0.4)^2 ≈ 0.50265 square centimeters.
