If 2 angles are supplementary:
α + β = 180°
α = 3 β + 54°
3 β + 54° + β = 180°
4 β = 126°
β = 126° : 4
β = 31° 30 `
α = 180° - 31° 30 `
α = 148° 30 `
Answer:
The measure of the first angle is 148° 30 `.
Answer:
The volume is 945.26
Step-by-step explanation:
The volume is 945.26 (this is only if this is a right cylinder)
volume of right cylinder formula = πr^2h
r = 4.5
We know that the circumference is 9.
circumference = 2πr
so, you would have to divide 9 by 2 to get the radius which is 4.5
h= 15 (already given)
then just plug it in!
π4.5^2(15)
π4.5^2 = 20.25π
20.25 x π = 63.6172512352
63.6172512352 x 15 ≈ 945.26
