Answer:


42.5\:\mathrm{m^2}

Explanation:

The area of a sector with measure
\theta in degrees is given by
r^2\pi\cdot(\theta)/(360), where
r is the radius of the sector.

What we're given:


  • r of 5

  • \theta of
    195^(\circ)

Solving, we get:


A_(sector)=5^2\pi\cdot (195)/(360)=13.5416666667\pi=42.5424005174\approx \boxed{42.5\:\mathrm{m^2}}

*Notes:

  • units should be in square meters (area)
  • the problem does not say whether to round or leave answers in term of pi, so you may need to adjust the answer depending on what your teacher specifically wants
