Answer:
Step-by-step explanation:
diameter = 20
radius = 10 units
Length of Chord = 16 units
The perpendicular from the center to a chord, bisect the chord.
So, base = 16/2 = 8units
Use Pythagorean theorem.
x² + 8² = 10²
x² + 64 = 100
x² = 100 -64
x² = 36
x = √36 = √6*6
x = 6 units
Answer: Yes it is reasonable.
Step-by-step explanation:
If all the numbers are rounded, 79 will be rounded to 80
12 to 10
and 11 to 10
If there are about 80 kids in 3rd grade, and about 20 kids in Mrs. Henry's class (because 10 girls plus 10 boys)
That means that 80-20
about 60 kids are not in Mrs. Henry's class
Hope this helped!
