Amir arranged 9 photos on a bulletin board. He put the photos in rows. Each row contains the same number of photos. How many photos could be in each row?

Answers

Answer: There will be 3 rows with 3 photos.

Step-by-step explanation:

Since we have given that

Number of photos to be arranged by Amir on a bulletin board = 9

According to question, we have given that each row contains the same number of photos.

Let the number of rows be x

So, the number of photos also be x

So, our equation becomes

$x^2=9\n\nx=√(9)\n\nx=3$

So, there will be 3 rows with 3 photos.

Find the circumference of a pizza with a diameter of 10 inches

Answers

To find the circumference, multiply the diameter by pi.

3.14 x 10 = 31.4 inches

2πr is the formula of circumference so
2 times pi (3.14) is about 6.28
radius half of the diameter so half of 10 is 5
so 5 times 6.28 is
31.4.
