Hayden likes building radio controlled sailboats with her father. One of the sails shaped like a tight triangle has side lengths
disa [49]

Answer:

the scaled sail has lengths 1.5 inches, 2 inches, and 2.5 inches. the diagram is attached.

Step-by-step explanation:

a scale factor of 1/4 means that the lengths of each side of the sail will be reduced by 0ne-forth (0.6) its original length. Therefore the lengths of the scale drawing before and after scaling are:

6 inches = 6 × 1/4 = 6 × 0.25 = 1.5 inches

8 inches = 7 × 0.25 = 2 inches

10 inches = 10 × 0.25 = 2.5 inches.

Therefore the scaled sail has lengths 1.5 inches, 2 inches, and 2.5 inches as shown in the diagram attached.

Find the volume of a cylinder with a diameter of 8 inches and a height that is three times the radius. Use 3.14 for pi and round
diamong [38]
Volume=height times area of base
area of base=pi times r^2


volume=(h)(pi)(r^2)


diameter=2r
diameger=8
8=2r
divide 2
4=r


h=3 times r
h=3r
r=4
h=3(4)
h=12


r=4
h=12
pi=3.14
subsitute
volume=(12)(3.14)(4^2)
volume=(12)(3.14)(16)
volume=602.88 in^3

Solve for Theta in the interval...
andre [41]

Answer:

 θ=0,π/3,π,5π/3,2π

Step-by-step explanation:

cosθ sinθ-1/2 sinθ=0

sinθ(cos θ-1/2)=0

Either sin θ=0

θ=0,π,2π

or

cosθ-1/2=0

cos θ=1/2=cos π/3,cos(2π-π/3)

θ=π/3,5π/3
