The set-up will represent a triangle whereby the :

  • Width = Height = 150 yards
  • Diagonal = Hypotenuse = 240 yards
  • Length = Base = ?

{a}^{2}  =  {c}^{2}  -  {b}^{2}  \\ {a}^{2} =  {240}^{2}  -  {150}^{2}  \\ {a}^{2} = 57600 - 22500 \\  \sqrt{ {a}^{2} }  =  \sqrt{35100}  \\ a = 187.3yards \: (rounded \: off \: to \: 1dp)

The radius of a wheel is 21m.how much distance will it covers when it rotates 5 times?​
mrs_skeptik [129]

Answer:

Distance = 660 meters

Step-by-step explanation:

Given the following data;

Radius, r = 21 m

Number of revolutions = 5 times

To find the distance covered;

The distance covered in one revolution is given by the circumference of a circle.

Mathematically, circumfeence of a circle is equal to;

C = 2πr

Substituting into the formula, we have;

C = 2 * 22/7 * 21

C = 44 * 3

C = 132 meters

Next, we find the distance covered;

Distance = Circumference * Number of revolutions

Distance = 132 * 5

Distance = 660 meters
