Assume the radius of a circle is

Mathematics
1 answer:
Lisa [10]2 years ago
7 0

Answer:

Step-by-step explanation:

They want you to see how radius is important.  Just remember that one radian is one radius,  that should help  you see why radius is important.

They ask for the unit circle ,  that is a circle of one unit for the radius,  which makes it super easy to calculate things for it,  they ask what is the area, which is that famous formula, πr^{2} ,  then they ask what's its circumference.  which is that other famous formula  2πr

so to go all the way around a circle of one unit radius,  it's  2π  exactly or about 6.28..... units,   call it meters, or feet or inches, it doesn't mater here.

the size of the circle doesn't matter here either,  b/c we are using the radius ,  that relaationship doesn't change ,  all circles,  what ever size , have this same relationship between the radius and radians.    :P  this is handy.

Jagan and Mithun calculated the value of 12 - 6 + 4.The steps are given alongside.
san4es73 [151]

Answer:

<h2>10.</h2>

Step-by-step explanation:

<u>Explanation:</u>

12 - 6 + 4

In order to solve this, we must use PEMDAS.

This is because there are more than one operations involved.

PEMDAS is the order in which you must solve the operations.

PEMDAS STANDS FOR:

  • Parenthesis
  • Exponential Notation (exponents)
  • Multiplication/division (do whichever comes first)
  • Addition/subtraction (do whichever comes first)

<u>Solve.</u>

Now, using PEMDAS, I will solve.

There are no parenthesis.

There are no exponents.

There is no multiplication nor division.

There is addition and subtraction.

12-6+4

12-6=6

6+4

Lastly, there is addition.

6+4=10

<u>Conclude:</u>

I, therefore, believe 12-6+4=10.

You did not clarify the answers of Jagan nor Mithun.

So, whichever person got the answer of 10 is correct.
