(a) \( 90^{\circ} \) The length of the perpentioular distance berween the two straight lines \( x+2=0 \) and \( x=3 \) equalls

Use geometric formulas to find the unsigned area between the graph of \( y=f(x) \) and the \( x \)-axis over the indicated interval. \( f(x)=x+10 ;[2,11] \) The area between \( f(x) \) and the \( x \)-axis is (Type an exact answer, using \( \pi \) as needed.)

В треугольнике \( A B C \) к стороне \( A B=6 \) см опущена высота, длина которой составила 22 см. Найди площадь этого треугольника и дай ттвет в квадратных сантиметрах.

Two gears are adjusted so that the smaller gear drives the larger one, as shown in the figure. If the smaller gear rotates through an angle of \( 270^{\circ} \), through how many degrees will the larger gear rotate?
