Answer:
r = 6 in
Step-by-step explanation:
=
r²h/3 = 216
r² (18/3) = 6 r² = 216
r² = 216/6 = 36
r = 6
definition is valid since center is exactly 1radius away from any point on the outersurface.
other figures do not fit this defn
5x =61-6
5x= 55
X = 55/5
X = 11
Answer:
11 1/4- pounds hamburgers can be made from 2 and 3/4 pounds of ground beef.
