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
B
Given
V =
Substitute the given values for B and h into the formula
V = = = 140 in³
t = 17.5
f = 12
interior corner angles in a square = 90 degrees
4t + 20 = 90
4t = 90 - 20
4t = 70
7f + 6 = 90
7f = 90 - 6
7f = 84
