Helen draws a random circle. She then measures its diameter and circumference.

She gets a circumference, C, of 405 mm correct to 3 significant figures. She gets a diameter, d, of 130 mm correct to 2 significant figures.

Helen wants to find the value of π using the formula π=C/d

Calculate the lower bound and upper bound for Helen's value of π. Give your answers correct to 3 decimal places.

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.
