area of a circle is PI x r^2

2 = d/2 = 5.4/2 = 2.7 cm

 using 3.14 for PI

3.14 x 2.7^2 = 22.89 square inches

360 degree in a circle, shaded area is 180 degree, which is 50%

 so 22.89 x .5 = 11.45 cm^2

Look at the equations below. Identify which equation has infinitely many solutions A. 21 + 2.5w = 6 +5.7w - 3.2w + 15 B. 9k +1 =
Volgvan

The equation that has infinitely many solutions in the options is 21 + 2.5w = 6 +5.7w - 3.2w + 15

<h3 /><h3 /><h3>What is an equation with an Infinitely many solution:</h3>

An equation with infinitely many solutions essentially have same thing on both sides.

Generally, a linear equation has infinitely many solution when the equations are equivalent. Let take for example:

  • 2y + 2= y + y + 2

The equation above have infinitely many solution because there is no actual value of y.

Therefore,

2y + 2 = 2y + 2

2 = 2

We can see both sides are equal to each other. So, this is an infinitely many solution.

Therefore, 21 + 2.5w = 6 +5.7w - 3.2w + 15 has an infinitely many solution.

  • 21 + 2.5w = 6 +5.7w - 3.2w + 15
  • 21 + 2.5w  = 6 + 15 + 5.7w - 3.2w
  • 21 + 2.5w = 21 + 2.5w
  • 21 = 21
  • 0 = 0
