FORMULA:
- Volume of cylinder = πr²h
- Volume of sphere = 4/3πr³
ANSWER:
Volume of capsule = 4/3πr³ + πr²h
πr²(4/3r + h)
- 3.14 × 2²(8/3 + 5.6)
- 3.14 × 4(2.6 + 5.6)
- 12.56(8.2)
- 102.99 or 103 rounded.
Now, Density = 0.7mg/mm³
It equals 2(x+1) blah blah blah
Answer and step-by-step explanation:
a. 4 litres in 5 minutes (litres per minute)
4 litres per 5 minutes means 4/5 litres per 1 min = 0.8 litres per minutes
b. 12 litres in 45 minutes = 12/3 litres in 45/3 minutes = 4 litres per 15 minutes
60 minutes = 4*15 minutes
4 * 4 = 16 litres per hour
c. 800 kilowatt hours in 2 months
1 year = 12 months = 2*6 months
kilowatt per year = 800 * 6 = 4800 kilowatt per year
Hope this helped :3
