Answer:
V_rocket = 44
ft^3 = 138.2 ft^3
Step-by-step explanation:
Volume of cone
V_cone = (1/3)*(
*(radius^2))*h
radius = 2ft
h = height of the cone = 3 ft
pi = 3.1416
V_cone = 4
ft^3
Volume cylinder
V_cylin = (
*(radius^2))*h_cyl
h_cyl = height of the cylinder = 10 ft
V_cylin = 40
ft^3
Volume rocket
V_rocket = V_cone + V_cylin = 4
ft^3 + 40
ft^3
V_rocket = 44
ft^3 = 138.2 ft^3
B. 15/8 because you count all of it
Answer:
15
Step-by-step explanation:
Finding total number of pupils(y)
3/y x 360°=27°
3x360°/y=27°
1080°/y=27°
1080°=27°y
1080°/27°=27°y/27°
40=y
Number of pupils who said that Maths was their favorite (z)
z/40x360°=135°
360°z/40=135°
360°z=135°x40
360°z=5400°
360°z/360°=5400°/360°
z=15
