20 tens ? Because 10x2 tens
Answer:
The radius of the semicircle is 4 cm
Step-by-step explanation:
The diameter of the semicircle is 8 cm
The radius is 1/2 of the diameter
1/2 *8 = 4 cm
The radius of the semicircle is 4 cm
Answer:
Interphase - First stage of Meiosis
Prophase I - Chromosomes pair up
Metaphase I = Chromosomes line up at equator
Anaphase I = Chromosomes pull part
Telophase I & Cytokinesis = Cell pinches in the middle
Prophase II = Two daughter cells formed
Metaphase II = Chromosomes line up at equator
Anaphase II = Sister chromatids pull apart
Telophase II & Cytokinesis = Cell pinches in the middle
Four grandaughter cells are formed.
I think I know what it forms - a cone!!
I'm guessing that the angles at the end are 10 degrees so that would make angle CAB equal 5 degrees.
Line AB would be the radius of the "upper cone".
Line BC is 12/2 or 6
tangent (A) = BC / AB
tangent (5) = 6 / AB
AB = 6 / tan(5)
AB = 6 / 0.087489
AB =

68.58 which is the radius of the "upper cone".</span></span></span>
Cone Volume = (PI * radius^2 * height) / 3
Cone Volume = (PI * 68.58 * 68.58 * 6) / 3
Cone Volume =

29,551
That is just the "upper cone volume. So, we multiply </span></span></span><span><span>

29,551 * 2
and get 59,102 which is the volume of the entire solid.
