Step-by-step explanation:
the formula for the area of a circle is πr^2
π=3.14
r= 1/2 of diameter = 6
3.14 x 6^2

In order to make 441 liters of Petrolyn oil, we need 189 liters of synthetic oil.
Given, for every 3 liters of synthetic oil, we use 4 liters of natural oil.
⇒ For 1 liter of synthetic oil, we will be adding 4/3 liters of natural oil.
Let 'x' be the liters of oil needed to make 441 liters of Petrolyn oil
⇒ For 'x' liters of synthetic oil, we will need 4x/3 liters of natural oil
Total Volume = 441 liters
Volume of Synthetic oil + Volume of natural oil = 441
x + 4x/3 = 441
⇒ (3x + 4x)/3 = 441
⇒ 7x/3 = 441
⇒ x = (441×3)/7
⇒ x = 189 liters
