Answer:
9 cm
Step-by-step explanation:
The volume of a square based pyramid is given as :
V = 1/3a²h
Where ; a = base edge ; h = Height
Volume, V = 48 cm³ ; a = 4cm
48 = 1/3 * 4² * h
48 = 1/3 * 16h
48 * 3 = 16h
144 = 16h
h = 144 / 16
h = 9 cm
Height = 9cm
Answer:
C(t)=0.10t + 25
Step-by-step explanation:
gradient = change in y/ change in x = 5/50 = 0.10
the y intercept is 25
so the equation is y = 0.1t + 25
Answer:
108 pi
Step-by-step explanation:
The formula for volume of a cone is (1/3) * π * r² * h
36 pi = (1/3) * π * r² * h
108 pi= π * r² * h
108 = r² * h
Formula for volume of a cylinder: πr²h
108 pi
