Question

Help with geo?

Answer 1

use the proportion of :
90/360 = length arc BC/circumference of circle

Answer 2

.25?

Answer 3

90/360 = 20/(2*pi*r)
1/4 = 10/pi*r
pi * r = 40
r = 40/pi
r = 40/3.14 = ...

Answer 4

12.73885350318471

Answer 5

yup, that's right

Answer 6

Could we do two more? :D Thanks for helping me!

Answer 7

okay

Answer 8

I need to find the length of segment MP if NP is a tangent to circle M

Answer 9

use the pythagorean theorem :
MP^2 = MN^2 + NP^2
MP^2 = 7^2 + 15^2
solve for MP

Answer 10

MP^2 = 49 + 225
MP^2 = 274
MP = 16.55294535724685

Answer 11

correct :)

Answer 12

Thanks!! Last one?:D

Answer 13

yeah :)

Answer 14

I need to find the measure of angle P, if the measure of angle M is 35 degrees (same circle)

Answer 15

<P + 35 + 90 = 180

Answer 16

solve for angle <P

Answer 17

180/360?

Answer 18

<P + 35 + 90 = 180
<P + 125 = 180
both sides subtracted by 125
<P + 125 - 125 = 180 - 125
<P = 55

Answer 19

Ooh, I have to get <P by itself, okay, I think Iget that, Thanks you C:

Answer 20

you're welcome ;)
