Find the radius
C = 2*pi*r = 26
r = 13/pi
----------
Vol+=+4%2Api%2A%2813%2Fpi%29%5E3%2F3
V+=+4%2A13%5E3%2Api%5E2%2F3+=+8788pi%5E2%2F3 cubic meters
V =~ 28911 cu meters

Hi

Note:  C(sphere) = 2pir  and V(sphere) = (4/3)pir^3

 V(sphere) = (4/3)pir^3    OR V(sphere) = (2/3)(2pir)*r^2

Question States:

 2pir = 26m,             therefore, V = (2/3)*26r^2 = 52/3r^2
