Answer:
3.98 cm
Step-by-step explanation:
V= πr²h
V= 200 cm³, r= 4 cm, h=?
h= V/(πr²)= 200/(3.14*4²)= 3.98 cm

Answer:
B is the answer
Step-by-step explanation:
Since there is already a 90 degree angle in the right triangle, the other two angles must add up to 90.
Plug 17 into both to find the smaller angle
So 33 is the answer or B
