sashaice [31]

Answer: $2.09ft^3$

Step-by-step explanation:

$Formula: V=\pi r^2 \frac{h}{3}$

Plug in your values.

$V=(3.14)(1ft)^2(\frac{2ft}{3})$

Answer: 1.1 Nm

Step-by-step explanation:

The formula for torque is T = r · F · sin θ

where θ = π/6, r = 20 cm = 0.2 m, F = 11 N

formula for converting radians to degrees is 1 rad × 180/π = 57.296°

θ = π/6 · 180/π = 30°

Substituting r into the formula for torque, we have

T = 0.2 x 11 x sin 30° = 0.2 x 11 x 0.5

T = 1.1 Nm
