Step-by-step explanation:
Surface Area of the Cylinder
= 2πr² + 2πrh
r = 4 in
h = 16 in
Surface Area :
= 2πr² + 2πrh
= 2π (4)² + 2π (4) (16)

y = number of days
35.50 + 18.25 y = 163.25
18.25 y = 163.25 - 35.50
18.25y = 127.75
y = 127.75 / 18.25
y = 7
so Martin has hired the machine for 8 days
( first day paid 35.50), then 7 days for 18.25
Lines are neither perpendicular nor parallel.
Step-by-step explanation:
Step 1:
In equation 1, Y = 5X + 7
In equation 2, Y = -2X -5
Step 2:
Slope Intercept form Y =mX +c
Where m = Slope
Slope of line 1 = 5
Slope of line 2 = -2
m1 is not equal to m2. Hence it is not parallel.
m1 × m2 is not equal to -1. Hence they are not perpendicular.
Answer:

Step-by-step explanation:
Similar shapes with scale factor
