let radius=5x,
height=12x,

volume of the cone=2512,
1/3 πr²h=2512,

1/3 × 3.14 × 5x × 5x × 12x =2512,

3.14 × 5×5× 4×x³=2512,

3.14×100×x³=2512,

then
x³=2512/314,

x³=8,

x=³√8,

then
x=2,

then
radius=5×2=10 cm,
height=12×2=24 cm,

then
slant height=26 cm,

therefore
C.S.A of the cone =πrl,

=3.14 × 10 × 26,

=816.4 cm²,

T.S.A of the cone =πr(l+r),

=3.14×10(26+10),

=3.14×10×36,

=1130.4 cm²
