Given that the diameter: d= 0.0625 inch.
So, radius of the wire : r = = 0.03125 inch
Now the formula to find the cross-sectional area of wire ( circle) is:
A = πr²
= 3.14 * (0.03125)² Since, π = 3.14 and r = 0.03125
=3.14 * 0.000976563
= 0.003066406
= 0.00307 (Rounded to 5 decimal places).
Hence, cross-sectional area of a wire is 0.00307 square inches.
Hope this helps you!
Answer:
Volume of the rolling pin = 246.09
Step-by-step explanation:
Length of larger cylinder L = 12 in
Diameter of larger cylinder D = 5 in
Diameter of two handles = 1.5 in
Length of two handles = 3 in
Volume of the rolling pin = Volume of two handles + Volume of larger cylinder
Volume of two handles = 2 ()
Volume of two handles = 2 (3.14 × × 3 )
Volume of two handles = 10.59
Volume of larger cylinder = ()
Volume of larger cylinder = (3.14 × × 12 )
Volume of larger cylinder = 235.5
Volume of the rolling pin = 10.59 + 235.5
Volume of the rolling pin = 246.09
Answer:
See explanation below
<u>Step-by-step explanation:</u>
range = 2200 - 300 = 1900
To find standard deviation, we have:
standard deviation = range/4 = = 475
The range rule of thumb estimate for the standard deviation is 475
Given:
Standard deviation, = 475
Margin of Error, ME = 100
= 1 - 0.90 = 0.10
Za/2 = Z0.05 = 1.64

n ≥ 60.68
≈ 61
