Answer:

64 pi

Explanation:

The circumference is given by

C = 2  pi r

8pi = 2 pi r

Divide each side by 2 pi

8 pi /2 pi = 2 pi r / 2 pi

4 = r

The radius is 4

The height is equal to the radius

h =4

We want to find the volume

V =  pi r^2 h

 = pi ( 4)^2 ( 4)

 =64 pi

Answer:

Vol = 64π

Explanation:

will make it simple and short.

given

circumference of a circle = 2πr = 8π

2πr = 8π

r = 4

h = r = 4                              

<u>required : Vol</u>

Vol = πr²h

Vol = π 4² * 4

Vol = 64π

The substage of sensorimotor development which this behavior reflect is an active experimentation.

<h3>What is an active experimentation?</h3>

An active experimentation can be defined as a substage of sensorimotor development which is typically characterized by the use of theories in order to proffer solutions to problems or make decisions.

In this context, we can infer and logically deduce that the substage of sensorimotor development which Dennis' behavior reflect is known as an active experimentation.

How can scientists know for sure that the cell theory is true? What evidence do we have to prove it?
Akimi4 [234]
I agree with it.The most widely accepted theory is that the first cells were created by groups of molecules working together to make the basic biomolecules (Carbs, Lipids, Proteins, Nucleic Acids). These biomolecules eventually found each other and supported each other creating cells. Over millions of years these unicellular organisms evolved into multicellular organisms, eventually leading up to humans and other common life forms today.
