Answer:

  • x =  {0, π/2, 3π/2, 2π}

Step-by-step explanation:

  • cotx cos x - cot x = 0
  • cotx( cosx - 1) = 0

1. <u>cotx = 0</u>

  • x = π/2 + πn
  • In the interval [0, 2π] we have π/2 and 3π/2

2. <u>cosx = 1</u>

  • x  = 0 + 2πn
  • In the given interval we have 0 and 2π

<u>So the solution set is:</u>

  • x =  {0, π/2, 3π/2, 2π}

Vsevolod [243]

Answer:

Capacity of tank = 44,000 l

Step-by-step explanation:

Given:

Height of tank = 3.5 m

Radius = 2 m

Find:

Capacity of tank

Computation:

Volume of cylinder = πr²h

Volume of cylinder = (22/7)(2)²(3.5)

Volume of cylinder = 44 m³

1m³ = 1000 l

So,

Capacity of tank = 44  x 1,000

Capacity of tank = 44,000 l
