we know that
For a spherical planet of radius r, the volume V and the surface area SA is equal to
The
ratio of these two quantities may be written as
we know
therefore
the answer is
Answer:
k = 63
Step-by-step explanation:
3 x 21 = 63
The triangles are congruent by the SAS congruence theorem. By extension, we can also say they are similar using a closely related theorem. Any time there are congruent triangles, they are automatically similar.
This is why the answer is choice C) Similar - SAS
Note how
SB = ET ... which forms the first "S" in "SAS"
angle ESB = angle SET ... which forms the "A" in "SAS"
SE = SE ... which forms the second "S" in "SAS"
this is why SAS works
Answer:
Using Pythagorean theorem:
Diagonal = sqrt( 60^2 + 100^2) = 116.62
