Answer 3

45/360 of the total area of the circle with radius (1/2)d = 15/2

Answer 4

What I still don't get it.

Answer 5

can you figure the area of the circle with diameter 15 ?

Answer 6

No

Answer 7

Area Circle = pi*radius^2

Answer 8

ok so it would be 3.14(7.5)^2

Answer 9

yes

Answer 10

The slice is 45 degrees of arc out of the full 360 degrees

Answer 11

176.625

Answer 12

ok and...

Answer 13

45/360 is the fraction of the full circle that the slice is

Answer 14

or 1/8

Answer 15

.125

Answer 16

yes, so you have 1/8 of the total area

Answer 17

I get it now. thx

Answer 18

cool, welcome

Answer 19

can you help me on another one?

Answer 20

Using the following equation, find the center and radius:
x2 + 2x + y2 + 4y = 20


The center is located at (1, 2), and the radius is 25.

The center is located at (-1, 2), and the radius is 25.

The center is located at (-1, -2), and the radius is 5.

The center is located at (1, 2), and the radius is 5.

Answer 21

complete the square on the x and y portions

Answer 22

to get into form

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

Answer 23

center (h,k) and radius r
