Find the area of the smaller sector

Digiron [165]

Since the radius is 6 inches, the area is

$A=\pi r^2=36\pi$ squared inches.

Now, the full circle is a sector given by a 360° angle. So, the area of a 140° angle will be proportionate:

$140\div x = 360\div 36\pi$

Solving for $x$ , we have

$x=\dfrac{36\pi\cdot 140}{360}=14\pi$

Use the intercepts from the graph below to determine the equation of the function.

Tems11 [23]

(-3,0) and (5, -2)

slope = (0 + 2) /(-3 - 5) = -2/8

y - 0 = -2/8 (x + 3)

y = -2/8 x - 6/8

8y = -2x - 6

2x + 8y = - 6

Answer is

D. 2x + 8y = -6
