L = length
W = width
P = perimeter
Equations:
L = 2W + 5
2L + 2W = P
P = 88
Solve using the equations above:
2(2W + 5) + 2W = 88
4W+ 10 + 2W = 88
6W + 10 = 88
6W = 78
w=16
the width is 16 centimeters
The blue one and the small purple one are similar because they have the same angles.
Answer:
Difference in volume between the two vinyl records = 3.872 in³
Step-by-step explanation:
Complete Question
2columbia records unveiled the lp (a vinyl record) in the waldorf astoria on june 18, 1948, in two formats: 10 inches in diameter, matching that of 78 rpm singles, and 12 inches in diameter. if the thickness of one vinyl record is 0.112 in, then determine the difference in volumes between the 10 inch and 12 inch records.
Each of the vinyl records will be modelled as a cylinder
Volume of a cylinder = πr²h
For the 12 inches diameter records.
r = (12/2) = 6 inches
h = thickness = 0.112 inches
Volume = π × (6²) × 0.112 = 12.672 in³
For the 10 inches diameter records
r = (10/2) = 5 inches
h = thickness = 0.112 inches
Volume = π × (5²) × 0.112 = 8.8 in³
Difference in volume between the two vinyl records = 12.672 - 8.8 = 3.872 in³
Hope this Helps!!!
