How precisely should you report a measured value when using a digital instrument?
an accurate guess using information from the problem
Read and record all digits, including zeros after the decimal point, exactly as displayed.
Record all digits that you can certainly determine from the scale markings and estimate one more digit
all of the above
We must analyze the problems and using common sense when recording data because - All measured values are estimates
True
situational
False
Analyze the image and select the formula to solve for the area of the ellipse
A = π ab
A = π (2a * 2b)
A = a/b * π
Yes
The formula for the surface area of a circle is the exact same formula of the surface are of the ellipse.
True
False
Sometimes the terms inscribed and circumscribed are associated with the creation of triangles and other polygons, as well as area calculations, is the triangle in the image inscribed or circumscribed?
inscribed
circumscribed
This formula (A = 1/2(bh)) will get you the area of an....
rhombus
polygon
oval
Triangle

work axis
2 d sketch
work plane
part file
In addition to angled work planes like the one in this image, you can also offset work planes or put them in a mid plane format to start sketches in specific areas?
False
True
Would an material with high density or low density be more likely to float on water?
High Density
Low Density
neither
_____________ is the amount of matter in an object or the quantity of the inertia of the object and ______________ is the force of gravity on mass
Density, mass
Density, weight
volume, mass
mass, weight
Which answer best describes volume?
is the amount of matter with in the density of a material
is the amount of three dimensional space enclosed by an object.
the surface area squared
the amount of mass or weight of an objects material
What could we do to measure the volume of a K-nex piece?
Record the water level in a graduated cylinder, put the k-nex piece in and record the new water level, then find the difference
use a dial caliper and find the radius then multiply by width x height
After you record the density you can multiply the density by the surface area squred
V = pi*r2*h - would give us the volume of a .....
rhombus
cylinder
triangle
the volume formulas are found on our PLTW engineering formula sheet
true
false
