10) for 4 tankers to draw from it, that means the volume of the fuel is the sum of all the others.

=> v=4(13,500)

v=πr²h

r=d/2=3.5m

v=54000litres

1L=1dm³

1dm=0.1m

=> 1dm³=(0.1)³m³

=> v=(22/7)(3.5)²h=(0.1)³(54000)

=> h=(7(0.1)³(54000)/22(3.5)²)

=> *h=108m*

10b) (5/3)(sin(x-29))=1/2

Cross multiply.

=> sin(x-29)=3/10

=> x-29=sin-¹(3/10)

=> x=29+sin-¹(3/10

=> *x≈46° to the nearest degree*…
