Find the radius of the circle given the area of the sector is 153.9 and the angle measure

zloy xaker [14]

Answer:

Step-by-step explanation:

area of sector = 153.9

or, (1/2) r²∅ = 153.9

or, r²∅ = 153.9 ×2

or, r²∅ = 307.8

or, r²× π/2 = 307.8

or, r² = 615.6/π

or, r² = 196

or, r=√196

r = 14

Answer:

$\displaystyle Bottom\:Right\:Graph$

Step-by-step explanation:

Use the zero-interval test [test point (0, 0)] to verify them as false or true, and to determine whether we shade the shared opposite portions [a shared portion that does NOT contain the origin] or the shared portions that DO contain the origin:

$\displaystyle 0 ≤ 0 - 2 → 0 ≰ -2$

$\displaystyle 0 < -3[0] - 2 → 0 ≮ -2$

So, this system will be shaded in a shared opposite portion.

*NOTE; Both inequalities have an identical y-intercept of $\displaystyle [0, -2],$ so both inequalities must intersect the y-axis at $\displaystyle [0, -2],$ and since there are already lines labeled as <em>dashed</em><em> </em>and solid, we do not have to worry about it in this case.
