Answer:
El área de superficie del cilindro es 6 · π cm², que es igual a 18.85 cm²
El volumen del cilindro es de 9 · π cm³, que es igual a 28.27 cm³
Step-by-step explanation:
Aquí tenemos
El área de superficie del cilindro = Perímetro de base × Altura
= π × D × h
Dónde:
D = diámetro de la base = 1.5 cm
h = Altura del cilindro = 4
∴ Área de superficie = π × 1.5 × 4 = 6 · π cm² = 18.85 cm²
Volumen del cilindro = Área de base × Altura = π · D² / 4 × h
= π × 1.5² / 4 × 4 = 9 · π cm³ = 28.27 cm³.
Answer:
17 , 65
Step-by-step explanation:
x+ y = 82
y = 4x - 3
=====================
Put the second equation into the first.
x + 4x - 3 = 82
5x = 85
x = 85/5
x = 17
17 + y = 82
x = 82 - 17
x = 65
Answer:
no. i mean if u wanna take my points ok thats fine but dont be upset when i take ur points

Answer:
The value of the constant in the equation below is 20.
Step-by-step explanation:
You are given the formula height = constant/width. All you have to do is take one of the points given on the graph and plug it in to the formula.
Example:
1 = Constant/20
Constant = 20
Answer:
The value of k that makes the relationship shown in the table below proportional is 
Step-by-step explanation:
The relation is proportional if 
Putting values of x and y to find k.
For x =2 and y =1 k is: 
For x =4 and y =2 k is: 
For x =6 and y = 3 k is: 
For x = 8 and y = 4 k is: 
For x =10 and y = 5 k is: 
So, The value of k that makes the relationship shown in the table below proportional is
