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
hope helped
Answer:
The circumference of the cookie is 37.68 inches.
Step-by-step explanation:

r is radius of circle
The circumference of circular shaped object is given by :
So, the circumference of the cookie is 37.68 inches.
Answer:
alternate exterior angle
Step-by-step explanation:
the angles are on the opposite side and on the exterior of the transversal. One is on the top side of the exterior and the twelve is on the bottom side of the exterior so thats why its an exterior angle. The reason why it is alternate is because its on opposite sides of the lines
Y = 3x - 9, because for a line to be parallel it has to have the same gradient (x value) as the first line, and y = 3x - 9 is the only equation with the x value of 3.
Answer:
its also again 40
Step-by-step explanation:
its L angle
