Answer:
3.14*4^2*10≈502.65
Step-by-step explanation:
(The zero is in the tenths place and it doesn't round up)
The formula for the volume of a cylinder is V=pi*r^2*h
pi=3.14
r^2=Radius Squared
h=Height

Answer:
B. The approximate length of EF is 4.47 units, and the approximate perimeter of triangle EFG is 12.94 units.
Step-by-step explanation:
First step is to determine the length of EF, since that will give us 2 sides of the triangle (since EG = EF).
From the diagram, we can easily make a rectangle triangle by dropping a vertical line from vertex E, let's name Z the meeting point of that line with the segment GF. Then we have a rectangle triangle EZF with a height of 4 and a base of 2, of which EF is the hypotenuse. So...
EF² = 4² + 2² = 16 + 4 = 20
EF = √20 = 4.47
Now that we have EF, we also have EG:
EF = 4.47
EG = 4.47
GF = 4 (visible on the graph)
Perimeter = 4.47 + 4.47 + 4 = 12.94 units.
Answer:
the unit rate is 1/10.
Step-by-step explanation:
4/40 divided by 4 equals 1/10
