volume of the cylinder is = π r²h = 294 π    -- given 
r and h are in the ratio = 7 : 6 
that means if r is 7x, then h is 6x 
putting these values in the volume formula - 
π into (7x)² into 6x = 294 π
π into 49 x² into 6x  = 294 π
294 x³ = 294 
x³ = 294/294 = 1 
so, x = 1 
⇒ r = 7 and h = 6 
so diameter is 7 into 2 = 14
