Answer:
29.5
Step-by-step explanation:
56 is the middle of the data set.
44+51 = 95
95/2 = 47.5
Q1 = 47.5
73+81= 154
154/2 = 77
Q3 = 77
77 - 47.5 = 29.5
29.5 is the interquartile range
Answer:
(1/3)πr2h.
Step-by-step explanation:
Volume of a cone:
V = (1/3)πr2h
Slant height of a cone:
s = √(r2 + h2)
Lateral surface area of a cone:
L = πrs = πr√(r2 + h2)
Base surface area of a cone (a circle):
B = πr2
Total surface area of a cone:
A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
