Step-by-step explanation:
Answer:
We suppose that a is the old price in cents
the total cost of 9.20 $ equals 920 cents
so we have 20 liters bought with the old price (a) and 10 liters with the new price (a + 2). This is translated into this equation where a is the old price therefore our quest to be answered
20 xa + 10 x (a + 2) = 920 (cents)
20 xa + 10 xa + 20 = 920
30 xa + 20 = 920
30 xa = 920 - 20
30 xa = 900
a = 900: 30
a = 30 (cents)
therefore the old price for 1 liter of petrol is 30 cents

Step-by-step explanation:
Answer:
Option (A)
Step-by-step explanation:
Volume of a cylinder is given by the formula,
V = πr²h
Here r = radius of the cylinder
h = height of the cylinder
Therefore, volume of a cylinder given in the question,
V = π(
)²(8)
= 648π
= 2035.8 km²
Volume of the given cylinder is 2035.8 km².
Option (A) will be the answer.
