Answer:
The mass of half a liter of water is 500g, that is, 0.5kg.
Step-by-step explanation:
Density is mass divided by the volume, that is:
Here, we have to be careful. Since the density is in grams per cm³, m has to be in grams and v in cm³.
We have that:
What is the mass of half a liter of water?
One liter is 1000 cm³.
So half a liter is 1000/2 = 500 cm³, which means that
Then
The mass of half a liter of water is 500g, that is, 0.5kg.
Answer:
The answer is 6256 of this question
Formula: SA = (2 × π(pie) × radius × height) + (2 × π(pie) × radius square.)
So the equation will be SA=( 2 × 3.14 × 2 × 4) + ( 2 × 3.14 × 2²)
Then, we will get ↓ ↓
SA= 50.24 + 25.12
<u>SA = 75.36 in</u><u>²</u>
Answer:
12
Step-by-step explanation:
square root of 8 = 2.82842712475
square root of 18 = 4.24264068712
4.24264068712 × 2.82842712475 = 12
