X - y + x + y = 180
2x = 180
x = 90
2x - 2y = x + y
x = 3y
y = x/3
y = 90/3
y = 30
x - y = 90 - 30 = 60
x + y = 90 + 30 = 120
2x - 2y = 180 - 60 = 120
Answer:
--- Curved Surface Area
--- Total Surface Area
Step-by-step explanation:
Given
Shape: Cylinder
-- height
--- radius
Solving (a): The curved surface area (CSA)
This is calculated as:
This gives:
Solving (b): The total surface area (TSA)
This is calculated as:
This gives:
Answer:
85,1 ft^2
Step-by-step explanation:
Semicircle area : 4^2π / 2 = 8π = 25,1 ft^2
Triangle area : (8 x 15) / 2 = 60 ft^2
Total Area = 60 + 25,1 = 85,1 ft^2
Answer:
A. 1.45
Step-by-step explanation:
To get a decimal from a fraction, divide the numerator by the denominator.
22 divided by 15 -> 1.45
