3y is the supplement of 141 so that means 3y+140=180 so y is 13.33. Since they give you 68, 68+13.33+x=180. So 81.33+x=180 and x=98.66.
The surface area of this shape is 42 square in.
Answer:
The radius of the water bottle is 2.25 cm
Step-by-step explanation:
The water bottle is said to be cylindrical, so its volume can be expressed as the volume of a cylinder.
Volume of a cylinder V = πr^2 h
Where;
h = height
r = radius
Making the radius the subject of formula;
r^2 = V/πh
r = √(V/πh)
Given:
Volume V = 121 cm^3
height h = 7.6 cm
π = 3.14
Substituting the given values;
r = √(121/(3.14×7.6))
r = 2.25 cm
The radius of the water bottle is 2.25 cm

Remember, taking the absolute value of a number always makes it a positive number.
Example 1) absolute value of -5 = 5
Example 2) absolute value of 7 = 7
Since -1 is within an absolute value, you can change -1 to 1
Then solve the expression by adding.
19 + 11 + 1 = 31
