6x3.14 = 18.84. That should be the answer
the answer is 120, i got this by finding 2/3 of 36 which is 24. i then multiplied 24 by 2, then multiplied 36 by 2, which gave me 48 and 72, and then i just added them together to get 120, hopefully this helps
The number on the left side of the decimal, write it as a large, in this case, three. The number on the right side of the decimal, write as a small number. Then put a ten under the five, and divide the two with a line. A way to remember this is - Imagine you have 3 cookies. The .5 represents a half of a cookie. You need to have all ten parts of the cookie to make a whole cookie. You'd need 5 more pieces of cookie to make 4 cookies. Hope this helps.
