A 60 minutes to complete the aspire reading test
F(x) = x²-x
g(x) =1/x
1) h(x) =f(x) -g(x) = (x²-x) - (1/x) = (x³-x²)/x (x≠0) =>
2)h(x) =f(x).g(x) = (x²-x).(1/x) =x(x²-1)
3)h(x) = f(g(x)) = (1/x)²-(1/x)
Answer:
Option D. 274.75 units²
Explanation:
From the question given above, the following data were obtained:
Radius (r) = 3.5 units
Height (h) = 9 units
Surface Area (SA) =?
The surface area of the cylinder can be obtained as follow:
SA = 2πr (h + r)
NOTE: Pi(π) = 3.14
SA = 2 × 3.14 × 3.5 × (9 + 3.5)
SA = 21.98 × 12.5
SA = 274.75 units²
Thus, the surface area of the cylinder is 274.75 units²
