What did I do wrong when finding out the sector area? I know the answer I got is wrong so can someone please help me

bonufazy [111]

I believe your mistake is that you are trying to use the sector area formula ti find arc length when there is already a formula for it.
The formula for it is
$2r\pi( \frac{degree}{360} )$
So first substitute the values in and then simplify!
$2(10.5)\pi( \frac{118}{360} )$
Now simplify!
21 × 118 is 2478 so it's
$\frac{2478}{360} \pi$
When divided ou and multiplied, this is 21.62cm!

Find the slope between points (2,3) and (-1,0)

Snezhnost [94]

Answer:

slope = 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (- 1, 0)

m = $\frac{0-3}{-1-2}$ = $\frac{-3}{-3}$ = 1
