    The perimeter of a circle is 2π.radius, as it is 1/4 of a circle this perimeter will be P=π.radius/2+2.radius

    No, itunot done yet. I want now that you solve 6.26+2.radius

    Circumference is \(2\pi r\) So since we havee 1/4 the circle, we have \(\dfrac{C}{4} = \dfrac{\pi r}{2}\)

    Then you add radius twice.

    So in fact P=3.14.2/2+2.2 P=3.14+4 P=7.14

    So perimeter is pretty much \(\dfrac{\pi r}{2}+r+r\)
