Need help ASAP. i forgot all the steps after the Area is solved with 5. or if 25pi is the right answer.
maxonik [38]

Answer:

42.5\:\mathrm{m^2}

Step-by-step explanation:

The area of a sector with measure \theta in degrees is given by r^2\pi\cdot\frac{\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 \frac{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

Two equations are given below:
Klio2033 [76]
First, you want all the variables to be on one side:
a - 3b = 4
a - b = -2

Now you want to eliminate one of the variables, in this case a is easiest.

Subtract the second equation from the first and you're left with:
-2b = 6
so b = -3

Sub the value of b back into either of the equations and solve for x:
a - (-3) = -2
a = -5

So your answer is (-5,-3)
