The surface area of the spherical ball is given as follows:
[tex]635.04\pi[/tex] yd².
The surface area of a sphere of radius r is given as follows:
[tex]S = 4\pi r^2[/tex].
In this problem, the diameter is of 25.2 yd, hence the radius is given by:
r = 0.5 x 25.2 yd = 12.6 yd.
Then the surface area in yd² is:
[tex]S = 4\pi (12.6)^2 = 635.04\pi[/tex].
