I’m gonna bet on D. Since I answered your question. Break my ankles✨
For this, all you need to do is subtract 2m on both sides, and your answer will be: -1 = m
Answer:
179.50 
Step-by-step explanation:
The equation for volume of a cone is:

The radius is half of the diameter so r= 3.5 in
The height is 4 times the radius so h=14

V= 179.50 
Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large (100000000000) or small (0.00000000001) to be written in a conventional manner.
The use of this notation is based on powers of 104
Example:
Big numbers:

Small numbers:

However, in areas such as physics and chemistry, scientific notation is important to make approximations such as:
mass of a proton
mass of an electron and others.
