Answer:
Second option: Surface area = 176*pi cm2
Step-by-step explanation:
The surface area of a cylinder is given by:
S = 2*pi*r^2 + 2*pi*r*h
Where r is the base radius and h is the height.
If we have that the diameter is 8 centimeters, the radius is 8/2 = 4 centimeters. So with r = 4 and h = 18, we have that the surface area is:
S = 2*pi*4^2 + 2*pi*4*18 = 176*pi cm2
So the answer is the second option.
Answer:
27 + 6x = 8.25x
Number of movies (x) = 12
Step-by-step explanation:
Given that:
VIP membership :
Membership fee = $27 per year
Amount per movie = $6
Hence ;
Membership fee + (amount per movie * number of movies)
27 + 6x - - - (1)
Non member :
Amount paid per movie = $8.25
amount per movie * number of movies)
8.25x - - (2)
Let Numbe of movies = x
In other to pay the same amount of money :
Equate (1) and (2)
Equation :
27 + 6x = 8.25x
8.25x - 6x = 27
2.25x = 27
X = 12 movies
Keeping in mind the formula for circumference is Pi x Diameter, you simply multiply 45 by pi.
This gives you 141.3716694
Answer:
Effective tax rate of Maria is 5.08%.
Step-by-step explanation:
Effective tax rate ETR = 
As a percent we can represent ETR = 
×100
In this question Maria has a total tax = $3072 and gross income = $60449
By putting these values in the formula ETR = 
×100 = 5.08
Therefore her effective tax rate is 5.08%.
