A winch is being used to pull a 3500-lb vehicle 30'. How much work is performed? Skip to navigation

105,000 foot-pounds.

Step-by-step explanation:

Work done = 3500 * 30 foot pounds

37.699 cm³

Step-by-step explanation:

Sa of cone:

pi×r×l + pi×r²

(3pi × l) + (pi × 3²) = 24pi

3l + 9 = 24

3l = 15

l = 5 (slant height)

Height: h

h² + r² = l²

h² + 3² = 5²

h² = 16

h = 4 cm

Volume = ⅓ × pi × r² × h

= ⅓ × pi × 3² × 4

= 12pi cm³

= 37.69911184 cm³
