Answer:

4.62 units

Step-by-step explanation:

Let's first find the length OR.

OR² = BR² + OB²

OR² = 5² + 12²

OR² = 25 + 144

OR² = 169

OR = \sqrt{19}

OR = 13

Let's find the area of triangle OBR.

Using the formula :

½bh

Where

b = BR

h = OB

Therefore, area of triangle OBR =

½ * BR * OB

= ½ * 5 * 12

= 30

From the diagram, triange OBR and OAR are parallel to each other, and they equal.

Thus, area of OBR = area of OAR

To find the length PA, we have :

Area of OAR = ½ * OR *PA

Let's make PA subject of the formula:

PA = \frac{area of OAR}{\frac{1}{2} * OR}

PA = \frac{30}{\frac{1}{2} * 13}

PA = 4.618 ≈ 4.62

PA = 4.62 units

The endpoints of the diameter of a circle are (−2, −3) and (4, −1). Which equation represents the circle?
Alika [10]

Answer:

The equation of circle is (x-1)^{2}+(y-2)^{2} = 18

Step-by-step explanation:

Given the endpoints of the diameter of a circle: (-2,-3) and (4,-1)

We know that the equation of circle is

(x-h)^{2} + (y-k)^{2}= r^{2}

where (x,y) is any point on the circle, (h,k) is center of the circle and r is radius of circle.

To find (h,k): the center is midpoint of diameter

Midpoint of diameter with end points (x1,y1) and (x2,y2) is given by

(  \frac{x1+x2}{2} , \frac{y1+y2}{2}  )

( \frac{-2+4}{2} , \frac{-3-1}{2}  )

(1,2)

Hence (h,k) is (1,2)

Substituting values of (h.k) and (x.y) as (1,2) and (4,-1) respectively in equation of circle, we get

(4-1)^{2} +(-1-2)^{2} = r^{2}

r^{2} = 18

Now substituting values of (h,k) and r^{2} in equation of circle, we get

(x-1)^{2}+(y-2)^{2} = 18

Hence the equation of circle is (x-1)^{2}+(y-2)^{2} = 18
