To find the circumference, all you need to do is multiply the radius by 2 pi (3.14) The answer would be 32 pi, which could also be 100.48. To get 100.48 you have to multiply 32 by 3.14 (pi)
Answer:
There's 3 total decimal places in both numbers.
Ignore the decimal places and complete the multiplication as if operating on two integers.
1 9
× 2
+ 3 8
= 3 8 Rewrite the product with 3 total decimal places.
Answer = 0.038
Therefore:
0.19 × 0.2 = 0.038
Step-by-step explanation:
I will take a go at this. Imagine you had 10 chairs to put people in, and you had 10 people. For the first chair, you can pick out of 10 people, for the second chair, you have 9 people to pick from, and so on until the last chair, where you don't have a choice. So, to find the possible ways you can sit people in the chairs, you do 10*9*8*7*6*5*4*3*2*1, or you can denote it as 10!, where ! means factorial. So you get 3628800, and at first you might think that would be the answer, but we are talking about a circular arrangement here. So, two arrangements would be counted as different just because it turns by one person (Shown in picture). So since we dont count the first one, it should just be 9! instead of 10! And 9! equals 362880 (One less zero than the other answer). That should be the right answer
What is the question again
