A container in the shape of of a frustum of a cone having diameters of its two circular faces as 35 cm and 30 cm and vertical height 14 cm, is completely filled with oil. if each of oil has mass 1.2 g, then find the cost of oil in the container if it costs $ 40 per kg.

Mathematics

Step 1:

Find two numbers that multiply to give ac (in other words a times c), and add to give b.

Step 2:

Rewrite the middle with those numbers:

Step 3:

Factor the first two and last two terms separately

example

Solution

3x 2 – 9x + x – 3 = 0

⟹ 3x (x – 3) + 1(x – 3) = 0

⟹ (x – 3) (3x + 1) = 0

⟹ x = 3 or x = -13
