Answer:

9. 16.6 units

10. 18.1 units

Step-by-step explanation:

9. We are given the opposite and adjacent sides of the angle 38 degrees, so we want to use tangent, which is opposite / adjacent:

tan(38)=13/x

x=13/tan(38) ≈ 16.6 units

10. We are given the adjacent and hypotenuse sides of the angle 25 degrees, so we want to use cosine, which is adjacent / hypotenuse:

cos(25)=x/20

x=20*cos(25) ≈ 18.1 units

Hope this helps!

What is the exact volume of a cylinder that has a height of 1.8 ft and a radius of 6.1 ft?
lozanna [386]
Cylinder area=height times area of base (area of base=area of circle)

height =1.8
radius=6.1
area of circle=pi times r^2


area of circle=pi times 6.1^2=37.21π
times height

1.8 times 37.21π=66.978π

volume=66.978π ft^3
