The formula for this is
. If the diameter is 8 the radius is 4, so filling in accordingly we have
and
which is
and when you multiply in 3.14 you get that A = 401.92 or B above.
I uploaded the answer to a file hosting. Here's link:
So we can setup variable equations for this:
so we're given that the length is 22feet longer than the width!
so as an expression length is equal to 22+w
and width as an expression is just w
so the formula for the perimeter for a rectangle is 2l+2w=perimeter
so fill it in now!
1616=2(22+w)+2w
1616=44+2w+2w
1616=44+4w
1572=4w
divide by four..
w=393
and length is simply 22 more than that as stated in the question!
so length is 415
dimensions are: 415x393
Answer: Becky used 1/2 yards of ribbon
Step-by-step explanation:
1/3=2/6
so 2/6 + 1/6 = 3/6 then simplify
