30 multiply by 2, 6 times

because it said that it would double every 4 hours

30×2×2×2×2×2×2=

60×2×2×2×2×2=

120×2×2×2×2=

240×2×2×2=

480×2×2=

P = 2 π r

The distance from the center of the pool to the fence is actually a radius of the circle:
r = 15 ft

P = 2 * 3.14 * 15
P = 94.2 ft² ≈ 94 ft²

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{1}}}}}$

Step-by-step explanation:

$\sf{ \frac{1}{2} \times 2}$
