exercice 28: cone de revolution 1
on considère un cone tel que SO=5cm et OSA=40°.
a) calcul la longeur de la generatrice SA du cone arrondie au mm.

b) calcul le rayon du disque de base arrondi au mm.

c) calcule le volume du cone au cm cube .

what are you trying to solve here

step-by-step explanation:

answer: its the third option.

step-by-step explanation:

i just took the test.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

just get this app called photo math it should be able to do those
