Answer:
A = 3.14
Step-by-step explanation:
A = π
A = 3.14 x 
(diameter = 2)
(remember, radius is half of the diameter)
(radius = 1)
A = 3.14

Answer:
V= 7,241.1
Step-by-step explanation:
V = 4/3 × π × r^3
V = 4/3 × 22/7 × 1,728
V = 88/21 × 1,728
V = 4.190 × 1,728
V= 7,241.1
We are given the statement that the strength, S, of a beam of width w andheight h is proportional to wh2. hence using k as the proportionality constant, the equation is S = k wh2. the exact width and height can be determined by applying optimization to the problem. optimization is taking the first derivative of an equation and equating then to zero
Answer:
1/12t=1/3h
t=?
1/12t*12=t
t=(1/3h)*12
t=4h
filling the tank takes 4 hours.
