Rounded to the thousands would be 307,000 and thousandths is 307.407
It is 2i I standing for imaginary since it is a negative
square root of -1×4
4 square rooted is 2
and a negative number square rooted is i

<em>Correction to your question text: diameter, not radius.</em>
The area of a circle is given by:

The radius is half of the diameter.

Substitute and solve.

Answer:
Increase the quotient by one
Step-by-step explanation:
Since in the question it is mentioned that There is a total of 33 cards and wants to put 4 cards on each page
So for determining the number of pages for put all of his cards
We should do increment in the quotient by 1 as there is a requirement of an additional page for the left cards
Therefore the above is the answer
1. 2*0.8 = 1.6 PQ = 1.6
2. arctan(14/12) = 49.4 degrees
3. 15 * cos(70) = 5.1 feet
4. x = 30 * cos(40) = 22.9813 = 23.0 miles
y = 30 *sin(40) = 19.2836 = 19.3 miles
