Area of sphere = 4πr² = 154 cm²
154 = 4 × 22/7 × r²
154 × 7 / 22 × 4 = r²
7 × 7 / 2 × 2 = r²
r = 7/2
Volume of sphere = 4/3 πr³
4/3 × 22/7 × 7/2 × 7/2 × 7/2
4/3 × 11 × 7/2 × 7/2
1/3 × 11 × 7 × 7
77 × 7 / 3
179.6 cm³

Surface area= 154cm2
4pi r2= 154cm2
r 2= 154× 88/7
R2=1936
R= (square root of )1936
=44 cm
Volume=4/3pi R3
4/3 × 22/7× 44×44×44=356961.52cm3
