Answer:
the price sold per kg to earn a profit of 20% is 7.2 kg
Step-by-step explanation:
The computation of the price sold per kg to earn a profit of 20% is shown below:
But before that the normal price per kg is
= 5.4 per kg × 100 ÷ 90
= 6 per kg
Now for 20% profit, the price per kg is
= 6 × (1 + 0.20)
= 6 + 1.2
= 7.2 kg
hence, the price sold per kg to earn a profit of 20% is 7.2 kg

Answer:
1696.460033 u^3
Step-by-step explanation:
1. The volume formula for a cylinder is
.
2. The radius is half of the width, So r would be 6. (12/2=6)
3. (6)^2 is 36. (6x6)
4. The height is given, which is 15.
5. Plug these numbers into the equation. It should be

6. This gives you your answer of 1696.460033 u^3.
