Answer 1

@Paynesdad i only understand from u

Answer 2

Ok the stepsfor 13-15 are : 1) Determine how many degrees in the shaded region. 2) Determine the radius. 3) Plug the values into the formula. \[ A= \left( \frac{mAB}{360} \right) \pi r^2\]

Answer 3

can u just solve one me pleasee its very hard for me

Answer 4

@papsmurf can u help me

Answer 5

ok with the 29-31 i cant help with but i can help you set up an equation for the measure of arcs.

Answer 6

Ok

Answer 7

i will give u a metall if anyone help me

Answer 8

\[45/360*2\pi(18)\]

Answer 9

you solve it this way it wil be like that you divide 45 by 360 and then multiply it by 36 (you mulitply the 2*18) and you leave your answers in the terms of pi

Answer 10

\[90/360*2\pi(16)\]

Answer 11

this is going in order by the number 13, 14, and here is 15

Answer 12

\[120-360=240/360*26\pi\]

Answer 13

now all you do is solve the equations but listen to @Paynesdad he knows what is talking about he gave you the equation thinking that you would be able to put the numbers into the spots next time look at it

Answer 14

ok

yes u do but can u show me how to solve equation please

Answer 22

do you have a phone?

Answer 23

no

Answer 24

i wish

Answer 25

ok well you take the numerator and divide it by the denominator and then you multiply the quotient by the radius which was multiplied by 2. in 15 you take the arc given and then you subtract it from 360 and then you divide your answer by 360 and multiply that by the diameter since the radius multiplied by 2 is the diameter there is no reason to double it

Answer 26

wow ok i will try i dont know anything because i came for sudan so no good english i just stated this school for begginners to months ago lol
