31. Make Sense and Persevere The bottom of a hemispherical cake has diameter 8 in.
8 in.
a. If the cake is sliced horizontally in half so each
piece has the same height would the top half
fit on a plate with diameter 6 in.? Explain.
b. If the cake is sliced horizontally in thirds so
each piece has the same height, would the
top third fit on a plate with diameter 5 in.?
Explain.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001

step-by-step explanation:

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
