Answer:
1.
circumference=diameter ×pi
=(29×2)× pi
=59×pi
area= pie × radius²
=pi×29²
=841pi
2.
circumference =pi×16.5
area=pi×8.25²
3.
153.94÷pi
radius=square root of 49.00062388
=7.000044563
times by 2
=14.00008913
4.
28.27÷pi
8.998620482=diameter
divide by two to find radius
4.499310241
then square
20.24379265
then times that by pi
=63.59775026

Answer: The dimensions of the rectangle are
Length = 75 and Width = 63
Step-by-step explanation: We would start with the information about the sides of the rectangle which states that the length is twelve inches more than it's width. In other words, if the width is represented by the letter w, then the length will be w + 12.
Also the perimeter of a rectangle is given as
2(L + W) where L is the length and W is the width of the rectangle
Therefore
Perimeter = 2( {w +12} + w)
276 = 2(2w + 12)
276 = 4w + 24
Subtract 24 from both sides of the equation
252 = 4w
Divide both sides of the equation by 4
63 = w
Therefore the width of the rectangle is 63 and the length is 75 (63 + 12).
L = 75 inches
W = 63 inches
