What is the the area of a sector of a circle with a radius of 9 centimeters and formed by a central angle that measures 120

dem82 [27]

Answer:

27π cm²

Step-by-step explanation:

step 1

Find the area of the complete circle

The area of the circle is equal to

A=πr²

we have

r=9 cm

substitute

A=π(9)²=81π cm²

step 2

Remember that the area of complete circle subtends a central angle of 360°

so

using proportion

Find the area of a sector formed by a central angle that measures 120°

81π/360°=x/120°

x=120°*81π/360°

x=27π cm²

What is the equation of a line that passes through the point (6, 1) and is perpendicular to the line whose equation is y=−2x−6y=

Mandarinka [93]

Lets get the negative reciprocal of the slope so we get
$m = \frac{1}{2}$
Now the equation that is perpendicular is
$y = \frac{1}{2} x + b$
Lets solve for b by plugging in the point (x,y)=(6,1)
$1 = \frac{1}{2} (6) + b \\ 1 = 3 + b \\ 1 - 3 = b \\ b = - 2$
Now plug that into the equation. So the equation of the line that is perpendicular and
passes through the point (6, 1) is
$y = \frac{1}{2} x - 2$
