The radius of the quadrant whose perimeter is 52cm is 14.56cm.
A quadrant is 1/4th of a circle, consisting of two radii, perpendicular to each other.
So, the perimeter of a quadrant consists of two radii and an arc, which is 1/4th the perimeter of a circle.
Therefore, the perimeter of the quadrant = 2r + (1/4)*(2πr) = 2r + (πr/2).
Now, we are given the perimeter of the quadrant = 52cm and are asked to find its radius.
We suppose the radius to be r cm.
Therefore, we can say that:
52 = 2r + (πr/2).
or, 52 = (4r + πr)/2
or, 52*2 = r(4 + π)
or, r = 104/(4 + π) = 14.56.
Therefore, the radius of the quadrant whose perimeter is 52cm is 14.56cm.
