Answer:
use this
Step-by-step explanation:
velocity = distance / time…. So distance = velocity x time
(48a^3 + 32a^2 + 16a) / 4a = ?
48a^3 / 4a = 12a^2
32a^2 / 4a = 8a
16a / 4a = 4
so
(48a^3 + 32a^2 + 16a) / 4a = 12a^2 + 8a + 4
Answer is D. 12a^2 + 8a + 4

Step-by-step explanation:
Answer:
6541.7 mm³ (nearest tenth)
Step-by-step explanation:

Given that the height is 40mm, h= 40mm.
Diameter= 2(radius)
Radius of cone
= 25 ÷2
= 12.5mm
Volume of cone

= 6541.7 mm³ (nearest tenth)
