Find the radius of a circle which has a sector area of 9 pi whose central angle is 90 degrees.

Greeley [361]

Answer:360/90 = 4

Total area = 4 times that of the sector.

Step-by-step explanation:

A 90 deg sector has 1/4 the area of the circle.

Total circle area = 4*9pi = 36pi

(x,-4) and (2,8); m=_3

DerKrebs [107]

$\bf (\stackrel{x_1}{x}~,~\stackrel{y_1}{-4})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{8}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{8-(-4)}{2-x}=\stackrel{\stackrel{m}{\downarrow }}{-3}\implies \cfrac{8+4}{2-x}=-3 \\\\\\ \cfrac{12}{2-x}=-3\implies 12=(2-x)(-3)\implies 12=-6+3x \\\\\\ 18=3x\implies \cfrac{18}{3}=x\implies 6=x$

Use the pythagorean theorem to find the distance between from A(5, -3) to B (6,0)

Orlov [11]

C. 3.16 is the right answer

Step-by-step explanation:

The distance formula used in coordinate geometry is derived from the Pythagorean theorem.

The distance formula is give by:

$d=\sqrt{(x_2-x_2)^2+(y_2-y_1)^2}$

Here (x1,y1) are the coordinates of first point and (y1,y2) are the coordinates of second point

Here,

(x1,y1) = (5,-3)

(x2,y2) = (6,0)

Putting the values in the formula

$AB = \sqrt{(6-5)^2+(0-(-3))^2}\\=\sqrt{(1)^2+(0+3)^2}\\=\sqrt{(1)^2+(3)^2}\\=\sqrt{1+9}\\=\sqrt{10}\\=3.16\ units$

The distance between two points is 3.16 units.

Hence,

C. 3.16 is the right answer
