Answer:

14  3/4 years

Step-by-step explanation:

Let's assume compound inflation.  The appropriate formula for that is:

A = P(1 + r)^t.

If we represent current prices by P, then double that would be 2P:

2P = P(1 + 0.048)^t    Find t, the time required for prices to double.

Then:

2   =  1.048^t

Taking the natural log of both sides, we get:

ln 2 = t·ln 1.048, so that:

t = (ln 2) / (ln 1.048)   =   14.78

At 4.8 inflation, with annual compounding, prices will double in approx. 14 3/4 years.

Answer: V≈900 ft³

Step-by-step explanation:

Formula

V=πr²h

Given

r=5 ft

h=12 ft

Solve

V=πr²h

V=π(5)²(12)

V=π(25)(12)

V=300π

V≈300(3)

V≈900 ft³

Hope this helps!! :)
