Area

Si el diámetro es 2 m entonces el radio es 1 m y el área es π (1 m)^2 o sea πm^2

The formula for the area of a circle when the diameter is given is $\dfrac{\pi}{4}d^2$ where $d$ is the diameter. So the area is $\dfrac{\pi}{4}(2^2)=$ $\boxed{\pi}$

Diamter = $2r = 2 \ m \\ \therefore r = \frac{2}{2} = 1 \ m$

Area = $\pi r^2 = \pi \times 1^2 = \pi \text{ m}^2$
