Find the length of arc ac. express your answer in terms of pi.

Given that: AB = 12 ft.

From the given figure we have;

diameter = AB = 12 ft.

ft.

Supplementary angles states that the two adjacent angles are sum up to 180 degree.

and are supplementary angles.

by definition of supplementary angles;

Subtract   from both sides we get;

To find the length of arc AC;

Formula for length(L) of arc is;

substitute the given values; we have;

ft

Therefore, length of arc AC is, ft

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
