The area of the sector formed by the 110 degree central angle is 40 units squared what is the radius
olga2289 [7]
We know that
area of the circle=pi*r²

if 360° (full circle) has an area of-------------> pi*r²
110°------------------------------> 40 units²
pi*r²=40*360/110--------> pi*r²=130.91------> r²=130.91/pi-----> r²=41.69
r=6.46 units

the answer is
the radius is 6.46 units

Y-5=-1/2(x+7) (find the slope)
sashaice [31]

It's the slope-point formula:

y-y_1=m(x-x_1)

We have:

y-5=-\dfrac{1}{2}(x+7)

Therefore, the slope m=-\dfrac{1}{2}

Select the equations of the lines that are parallel to the line whose equation is y = 3x + 5. There might be more than one answe
o-na [289]
Parallel means they have the same slope.
The given equation has a slope of 3. Slope intercept equation: y = mx + b
a. 6x + 2y = 12
Subtract 6x from both sides.
2y = - 6x + 12
Divide both sides by 2.
y = -3x + 6 Not parallel

b. -3x + y = 8
Add 3x to both sides.
y = 3x + 8 Parallel

c. 3y = 9x
Divide both sides by 3
y = 3x Parallel

d. y = -1/3x Not parallel

B and C are parallel
