slega [8]

Answer:

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

Circle X

$rx=6\ units$

$Cx=12\pi\ units$

Circle Y

$Cy=6\ units$

Find the radius ry

we know that

$Cy=2\pi ry$

substitute the value of Cy

$6=2\pi ry$

$ry=\frac{6}{2\pi }$

Remember that the value of rx is $rx=6\ units$

substitute

$ry=\frac{rx}{2\pi }$

The end point P of a line segment PQ(-3,6) and its mid point is (5,8) Find the coordinates of the end point Q

Georgia [21]

Answer:

(13, 10)

Step-by-step explanation:

Let Q have coordinates x and y

Using midpoint formula we find the values of x and y

(- 3 + x)/2 = 5 ⇒ -3 + x = 10 ⇒ x = 10 + 3 ⇒ x = 13
(6 + y)/2 = 8 ⇒ 6 + y = 16 ⇒ y = 16 - 6 ⇒ y = 10
Q = (13, 10)

Step-by-step explanation:

The volume of the cubes is 1/64. Because 1/4*1/4*1/4=1/64.

The volume of the prims is 14/4 because 7/4*2*1=14/4.

Take the 14/4 and divide it by 1/64.

Which equals 896/4 = 224

Hope that helped.
