A copper key is placed in a cylindrical container with a 3-cm diameter. The water level rises from 14 cm to 14.6 cm. What is the volume of the key? Options:

The volume is about 4.24 cm^3.

The volume is about 3.72 cm^3.

The volume is about 2.96 cm^3.

The volume is about 1.41 cm^3.

The volume is about 4.24 cm^3.

Step-by-step explanation:

From the question we are told that:

Diameter

Radius

Height risen

Generally the equation for Volume of a Key is mathematically given by

Since Volume of a cylinder is Given as

Therefore

Correct Option A

The volume is about 4.24 cm^3.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

correct answer:

b.(19,-2)
