From the points given we know that the rectangle is 3 points wide and 2 points tall. If we rotate it
around the x axis then we will receive the lying cyllinder which will be 3 points tall and 2 points wide (so its radius is 2/2 = 1 point). Now we can find the surface area of the cyllinder using appropriate formula:
Answer:
Step-by-step explanation:
P = m/v
Where p is density m is mass and v is volume
Putting values of m and v
P = 52.4/ 13.5
P =3.88
The circumference of a circle is 2piR or Dpi. so this would be 10pi
Answer:
Assuming you mean 2+ (4/5), no
Step-by-step explanation:
=2* (5/5) + (4/5)
=10/5 + 4/5
=14/5
if you mean (2+4)/5,
its 6/5, so still not 1/3
