Someone please help.

The top right

Step-by-step explanation:

the one closest to the clear and check button

I believe is the second answer

Step-by-step explanation:

3 x 9 = 27

(each row is 9 circles long)

o

o (and its 3 circles tall)

o

which means 3 x 9, if we pay close attention to the options we can see that the second choice is 3 circles tall and 9 circles wide resulting in the equation of 3 x 9 which is 27 in total.

Hope this helped

step-by-step explanation:

just plug in each number for x and see which ones work and don't

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
