184.6cm³ up you are rounding to the nearest tenth 184.56cm³ if you are rounding to the nearest hundredth
It's a hemisphere instead of a sphere so the formula is 2/3×π×r³ which gives us the equation of 2/3×π×4.45³ snd the reason we use 4.45 is because the diameter is 8.9 so we have to divide that by 2 to get the radius which is 4.45
