Given:

  • Angle JKL= 112 units
  • JK= 7 units

To find:

  • The area of sector JKL to the nearest hundredth.

Solution:

JKL occupies [tex]\frac{112}{360}[/tex] of the circle.

Radius of the circle is 7 units.

First, we'll have to find the area of the circle.

[tex]\large\boxed{Formula: a= \pi {r}^{2}}[/tex]

Let's solve!

Let's substitute the values according to the formula.

We are finding it in terms of pi.

[tex]a= 7×7[/tex]

[tex]a= 49 \pi[/tex]

Now, we can find the area of sector JKL.

[tex]= \frac{112}{360}× 49 \pi[/tex]

[tex]= 47.89183467 \: {units}^{2}[/tex]

Now, we'll have to round off to the nearest hundredth.

The value in thousandths place is less than 5 so we won't have to round up.

Final answer:

[tex]\large\boxed{a= 47.89 \: {units}^{2}}[/tex]

Hence, the area of sector JKL is 47.89 square units.
