Answer:
3.16
Step-by-stepp explanation:
The volume of a cylinder is given by the expression:
V = πr²h ----------*
314cm³ = 22/7 X r² X 10cm
314cm³ = 220/7 X r²
r² = 314 X 7 ÷ 220
r² = 2198 ÷ 220
r² = 9.99
r =√9.99
r = 3.16
Hence the radius of the cylinder is 3.16
Answer:
a = 2
b = 3
Step-by-step explanation:
Since they both are points on the line they'll both satisfy the line equation, and we can substitute their x-coordinate and y-coordinate into the equation, then solve the system of equations we obtained:
3a = 6
-3a + 4y = 6
From the first one we find that a = 2. Let's substitute in the second:
-3*2 + 4y = 6
y = 3

Answer:
the cost is
Step-by-step explanation:
observing the graph
we know that
For the interval of x------> -----> the cost is
For the interval of x------> -----> the cost is
For the interval of x------> -----> the cost is
For the interval of x------> -----> the cost is
In this problem we have
hours and minutes
therefore
the value of x belong to the interval
the cost is
