Answer:
Step-by-step explanation:
Looking at the graph, we can see the domain to be from (0 , 2π).
Now we have to find one period that corresponds to cos(x).
The half-period of cos(x) for this graph appears to be pi/3 and adding another pi/3 gets us 2pi/3 to be our cosine period.
b = 2pi/3
a is the same range as cos(x). Range: (0,0)
y = [a] * cos ([b]*x)
y = [1] * cos([2pi/3]x)
Answer:
131.88 cm²
Step-by-step explanation:
The surface area of a cylinder is 2πr² + 2πrh
Since the figure we are dealing here is a quarter of a cylinder, divide the equation by 4.
New equation =
We know:
r = 6 cm
h = 8 cm
Now substitute the values and solve:
= 131.88 cm²
