Cornelius is building a solar system model. He plans on making a circular ring around one of the planets out of wire. He wants to know how long he should make the wire to position around the planet. Select all the formulas that could be used to determine the length of the circular ring.

C = 2πr
A = πr2
C = πd2
A = πr
A = πd
C = πd

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
