I’m struggling so much please help

see explanation

Step-by-step explanation:

The volume (V) of wood used is calculated as

V = volume of cone - volume of cylinder

V = πr²h - πr²h

diameter of cone = 12, so radius = 12 ÷ 2 = 6

V = π × 6² × 14 - π × 4² × 3

   = π × 36 × 14 - π × 16 × 3

   = π × 12 × 14 - 48π

   = 168π - 48π

   = 120π cm³

Cone volume:

Cylinder volume:

Volume of wood:

Hope this helps

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
