Answer:
W = 21.44*10⁶J
Step-by-step explanation:
Given
y = x² (0 < x < 4)
γ = 10000 N/m³
W = ?
If we apply
y = 4² = 16 = h
y = x² ⇒ x = √y
then
V = π*(√y)²*dy = π*y*dy
W = (γ*V) *(16-y) = γ*π*y*dy*(16-y)
⇒ W = γ*π*∫y*(16-y)dy = γ*π*(8y²-(y³/3))
finally we obtain (0 < y < 16)
W = γ*π*(8y²-(y³/3)) = 10000*π*(8*16²-(16³/3)) = 21.44*10⁶J
Answer:
28.478
Step-by-step explanation:
<h3>1)x=180°−(50°+60°) x = 180 ° - ( 50 ° + 60 ° ) =180°−110°=70°</h3>
<h3>2)x=180°−(30°+90°) Since it is a right angle so the third angle is a right angle. ...</h3>
<h3>3)x=180°−(30°+110°) x = 180 ° - ( 30 ° + 110 ° ) =180°−140°=40°.</h3>
<h3>4)Here; 50°+2x=180° Or, 2x=180°−50°=130° ...</h3>
<h3>5)This is an equilateral triangle. ...</h3>
<h3>6)This is a right angled triangle.</h3>
