The first is the correct
Δ ZYB ≈ Δ OWR by SSS
because:
ZB = OR = 5
ZY = OW = 3
YB = WR = 5.5
Answer:
150.83 (cm²).
Step-by-step explanation:
1) the area of the bottom and top is: A₁=π*r²*2=2*3.1415*4≈25.13 (cm²);
2) the length of the circle in the bottom/top side is: l=2*π*r=2*3.1415*8≈12.57 (cm);
3) the area of the side surface of the cylinder is: A₂=l*h=12.57*10=125.7 (cm²);
4) the required area of the cylinder is:
A=A₁+A₂=25.13+125.7=150.83 (cm²).
It would be the points (0,80) and (15,10)
Answer:
5 + 2.5x <20
Step-by-step explanation:
subtract 5 from each side so now it is 2.5x < 15
divide both sides by 2.5, so now it is x < 6
so it will be LESS THAN 6 months before her hair is LESS THAN 20 centimeters
