If the three sets of corresponding sides of two triangles are in proportion, the triangles are similar. SAS for similar triangles is NOT the same theorem as we used for congruent triangles.
Step-by-step explanation:
Scale factor = 4/3. Therefore radius if larger cone = 4r/3 where r is the radius of the smaller cone and height of larger cone = 4h/3 where h is the height of the larger cone.
So ratio of volumes = r^2 * h/(4r/3)^2 * 4h/3) = 9/16 * 3/4 = 27/64
30 is a similar process except it's cylinders so find the scale factor and go on with that problem.
For this case we can select the objects that can physically be measured in centimeters.
We must have in mind that all objects can be measured in centimeters.
For this, there is the conversion of units.
However, sometimes, for very large measurements, it is not convenient to use centimeters.
Therefore, from the list mentioned, Brad could have measured in centimeters:
height of a person
width of a screen in a theater
He could have used a measuring tape and a rule for such purposes.
Answer:
C.height of a person
F.width of a screen in a theater
