Which of these is a prime number?<br> 733<br> 712<br> 702<br> 725
marishachu [46]

Answer:

733

Step-by-step explanation:

712 and 702 end in 2, so they're divisible by 2.

725 ends in 5, so it's divisible by 5.

733 is not divisible by 2.

7 + 3 + 3 = 13, so 733 is not divisible by 3.

It looks like 733 is the prime number.

zvonat [6]

Answer:

19.14

Step-by-step explanation:

You have a half circle and a square, look at them separate then add for the area.

Circle

Your radius is half the diameter, so 4/2

Radius  = 2

A = 3.14 * radius\\A = 3.14 * 2\\A = 6.28

This is for the entire circle, half of that would be 3.14

Square

A = 4^{2} \\A = 16

Add them both together for a total area of 19.14 square miles
