How do i find each product by factoring the tens? 3x2, 3x20, and 3x200

Well, since it only asking about the product, you don't have to multiply the result 
The product would be :
3 x 2 = 6
3x 20 =  3 x 2 x 10  = 60
3 x 200 = 3 x 2 x 10 x 10 = 600

hope this helps

the answer would be c ≈ 18.852*3.14= 6.286.28*3=18.85
