Applying the formula for the area of a sector and length of an arc, the value of k is calculated as: 27.

<h3>What is the Area of a Sector?</h3>

Area of a sector of a circle = ∅/360 × πr²

<h3>What is the Length of an Arc?</h3>

Length of arc = ∅/360 × 2πr

Given the following:

  • Radius (r) = 9 cm
  • Length of arc = 6π cm
  • Area of sector = kπ cm²

Find ∅ of the sector using the formula for length of acr:

∅/360 × 2πr = 6π

Plug in the value of r

∅/360 × 2π(9) = 6π

∅/360 × 18π = 6π

Divide both sides by 18π

∅/360 = 6π/18π

∅/360 = 1/3

Multiply both sides by 360

∅ = 1/3 × 360

∅ = 120°

Find the area of the sector:

Area = ∅/360 × πr² = 120/360 × π(9²)

Area = 1/3 × π81

Area = 27π

Therefore, the value of k is 27.

*ੈ✩‧₊˚<br> raise the fraction to higher terms as indicated <br><br> 2/3 to twenty-firsts
DIA [1.3K]

The appropriate fraction when the number is raised to higher terms will be 14/21.

<h3>How to compute the fraction?</h3>

It should be noted that when we sat raising that fraction to higher terms, it implies that changing the numerator and the denominator to higher numbers to reflect the fraction.

Here, the given number is 2/3. When it's raises higher, the appropriate fraction will be:

2/3 = x/21

x = (2 × 21)/3

x = 42/3

x = 14

Therefore, the fraction will be 14/21.
