Answer:
122.7792 sq. m
Step-by-step explanation:
diameter= 8.4 m
therefore, radius = r = 4.2 m.......( as radius is 1/2 of diameter)
height = h= 12 m
only the exterior is to painted so the total surface area of the cylinder is taken,
total surface area of cylinder = 2π r( h+r)
=2* 3.14* 4.2*(12+4.2)
=122.7792 sq. m
Answer:
Three non-collinear points determine a plane.
Step-by-step explanation:
This statement means that if you have three points not on one line, then only one specific plane can go through those points. The plane is determined by the three points because the points show you exactly where the plane is

Yes, the 3 feet are important.
<span>You can consider the datum (y=0) at 3' from the ground, and the ground is therefore at -3 feet. </span>
<span>The vertical initial velocity, vy, is u*sin(θ), so it gives </span>
<span>vy=55sin(44°)=38.21 approx. </span>
<span>The (vertical) distance travelled is given by: </span>
<span>S=vy*t-(1/2)gt² </span>
<span>where </span>
<span>S=-3 (ground) </span>
<span>vy=55sin(44°), and </span>
<span>g=32.2 ft/s² </span>
<span>Solve for t. </span>
<span>I get -0.08 and 2.45 s.</span>
If a₁ = 5 and 
, then
a₂ = a₁ - 3 = 5 - 3 = 2
a₃ = a₂ - 3 = 2 - 3 = -1
a₄ = a₃ - 3 = -1 - 3 = -4
a₅ = a₄ - 3 = -4 - 3 = -7
a₆ = a₅ - 3 = -7 - 3 = -10
