Answer:
x=1, y=2. (1, 2).
Step-by-step explanation:
-3x+10y=17
3x+7y=17
---------------
17y=34
y=34/17
y=2
3x+7(2)=17
3x+14=17
3x=17-14
3x=3
x=3/3
x=1

Answer:
The answer to your question is Volume = 3.30 cm³
Step-by-step explanation:
Data
Volume = ?
height = 14.9 cm
circumference = 2.9 cm
Process
1.- Calculate the radius
circumference = 2πr
-Substitution
2.9 = 2πr
-Solve for r
r = 2.9/2π
r = 1.45/π cm
2) Calculate the volume of the cone
Volume = 1/3πr²h
-Substitution
Volume = 1/3π(1.45/π)²(14.9)
-Simplify
Volume = (1.04)(0.213)(14.9)
Volume = 3.30 cm³
