Answer: 414.48
Step-by-step explanation:
r: the radius of the base
h: height
The volume of a cone is given by:
V = π ∙ r2 ∙ h / 3,
where π ∙ r2 is the base area of the cone.
π defines the ratio of any circle's circumference to its diameter and is approximately equal to 3.141593, however the value 3.14 is often used.
Answer:
a)
v=<400, 450+3t, 600-9.81t> m/s
r=<400t, 450t+3
/2, 15+600t-9.81
/2> m/s
b) attach file
c) t=122.324s
d) z=18369.9854 m
Step-by-step explanation:
a)
The equation for velocity of each component is v=
+at, in this case the x-axis component has acceleration 0
, the y-axis component has acceleration 3
and the z-axis component has -g
, where g=9.81
.
The equation for position of each component is x=
+
t+a
/2,
with <
,
,
>=<0,0,15>.
c) This time is t when z=0, with positive sign.
d)Solving the equation
=
+ 2*a*(z-
) for z, with
=0.
3. 60 divide by 360 times pi times (8)2=33.51 squared inch
4. 120divide by 360 times pi times (5 over 2)2=40.9 squared inch
If he counts 76 feet, that means there’s 38 animals in total, because animals have 2 feet. 76/2=38
Hope that helps..!
Answer:
x=12.
Step-by-step explanation:
Let's get this straight out of the way, the 3 angles of a triangle ALWAYS add up to 180. Now that that's said, lets begin. Since the opposing side of an angle is the same as the regular side, we simplify to get: 5x+120=180. 180-120=60. so 5x=60. 60/5=12. so x=12.
