The diameter of a circular glass lens is 8.7 centimeters. paige uses the edge of the lens to trace a circle on a sheet of paper. what is the estimated circumference of the circle?
1. 13.659 centimeters
2. 27.318 centimeters
3. 54.636 centimeters
4. 237. centimeters

2.  27.318 centimeters

Step-by-step explanation:

We know that the circumference of a circle is given by :-

, where d is the diameter of the circle.

Now, the diameter of the given circle = 8.7 centimeters

Therefore, the circumference of the circle will be :-

Since, the estimated value of ,

Therefore,

Hence, the estimated  circumference = 27.318 centimeters.

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.
