Answer:
Circumference ≅ 195 mm
Step-by-step explanation:
The circumference of a circle is equal to: 
Since
we can replace that in the circumference equation giving us:

We know Diameter = 622 mm and pi = 3.14 so:

Answer:
the answer is 1/3 pie r2h
Step-by-step explanation:
The volume of a cylinder is given by πr²h where, r is the radius of the cylinder and h is the height of the cylinder.
Also r=d/2 , where d is the diameter of the cylinder.
Therefore if the diameter is halved, the radius also gets halved ,i.e., it becomes r/2. Therefore the new volume = π(r/2)²h
=π(r²/4)h
=(1/4) πr²h
Therefore the volume becomes one-fourth of the initial volume.
Answer:
Draw intersecting arcs inside the angle from points D and E without changing the compass width.
Step-by-step explanation:
The next step from here, will be :
Draw intersecting arcs inside the angle from points D and E without changing the compass width.
After this, draw a straight line from B to the arcs made from above step. This line is the angle bisector.
