Divide 1920 by 40
Then multiply the number by 2
You will get 96
Then multiply it by 30
Step-by-step explanation:

Answer:
10x+2y
Step-by-step explanation:
combine like terms
Volume = area of base *height
20 = pir^2 *h
20 = 3,14*4*h
h = 20/12,56 = 1,59 rounded 1,6
- using the triangle formed by radius,the height of cup and the slant height of cup so we can writing that
tan ß = h/r so tan ß = 1,6/2 = 0,8
tan ß = 0,8 so ß = arctan 0,8 = 38,6 degrees so 39 degrees
