Radius is 7 cm surface is 880 cm square what is the length of the cylinder?
1 answer:
Answer:
Step-by-step explanation:
surface area = 2πrL + 2πr² = 14πL + 98π
14πL + 98π = 880
14πL = 880-98π
L = (880-98π)/(14π) ≅ 55.9 cm

Answer:
x=3 and y=2
Step-by-step explanation:
1.) 4x+3(5x-13)=18
expand into 4x+15x-39=18
18+39= 57
15x+4x= 19x
57/19= 3 so x=3
substitute 3 into y= 5x - 13
and you get 2 so y=2
