Answer:

40.21 unit^2.

Step-by-step explanation:

The area of the sector = 0.5 C r^2 where C = the angle and r = the radius.

= 0.5 * (8/5) π * 4^2

= 40.21 unit^2.

$\huge\text{Hey there!}$

$\mathsf{20\dfrac{4}{8}+ 19 \dfrac{7}{9} + 15 \dfrac{3}{36}}$

$\mathsf{= \dfrac{20\times8 + 4}{8}+\dfrac{19\times9 + 7}{9}+ \dfrac{15\times36+3}{36}}$

$\mathsf{= \dfrac{160 + 4}{8}+\dfrac{171 + 7}{9}+ \dfrac{540 + 3}{36}}$

$\mathsf{= \dfrac{164}{8}+ \dfrac{178}{9}+ \dfrac{543}{36}}$

$\mathsf{= \dfrac{725}{18} + \dfrac{543}{36}}$

$\mathsf{= \dfrac{1,993}{36}}$

$\mathsf{\approx 55\dfrac{13}{36}}$

$\huge\textsf{Therefore, your answer should be:}$

$\huge\boxed{\frak{55\dfrac{13}{36}}}\huge\checkmark$ $\large\textsf{Or even }\rightarrow$ $\huge\boxed{\frak{\dfrac{1,933}{36}}}\huge\checkmark$ $\large\textsf{(Either should work because they are both EQUIVALENT to each other)}$
