I think you are asking me for the change in degrees, so its
89-62=27
let's recall Cavalieri's Principle, <u>solids with equal altitudes and cross-sectional areas at each height have the same volume</u>, so even though this cylinder is slanted with a height = x and a radius = 8, the cross-sectional areas from the bottom to top are the same thickness and thus the same area, so its volume will be the same as a cylinder with the same height and radius that is not slanted.

There is an app called socratic, also if this assignment goes with a text book there is an app called sladder that has all textbook answers with work
Answer:
Option B is right
Step-by-step explanation:

(One tailed test at 5% significance level)
n =16 and x bar =1.97
s =0.1
Std error of mean = 
Mean diff = 
t statistic =Mean diff/se =-1.2
df =16-1=15
p value =0.124375
(B) do not reject the null because the test statistic (-1.2) is > the critical value (-1.7531).
