Circunference=pi times diameter
diameter=16in
circunfernce=16pi in
that is exact because pi is irrational
if we were to aprox pi to 3.14 hen
16 times 3.14=50.24
so answer is 16pi or 50.24 in
Answer:
Part 5) The roots are x=-3 and x=1.5
Part 6) The solution on a number line is the shading area below of the line y=-1/3 (close circle)
Step-by-step explanation:
4y=7x
The sum of the numbers is 22
so, x+y=22
x=(22-y)
by substitute (22-y) for x in the first equation.
Assume the mattress have no width, only length.
By Pythagoras' Theorem, √(72^2 + 80^2) = 107.6 inches.
