Answer:
D
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V =
πr³ ( r is the radius ), thus
V =
π × 5³
=
π × 125 =
π =
π units³ → D

we may take the time taken by the machine as x

Answer:
Width: 12 ft
Maximum area: 144 ft²
Step-by-step explanation:
A = 24x – x²
A = –x² + 24x
A = –(x² – 24x)
A = –(x² – 24x + 144) + 144
A = –(x – 12)² + 144
Therefore, the maximum area of 144 ft² occurs at x = 12 ft.
