Answer:
Step-by-step explanation:
Answer:
The solid formed is a cylinder
The total surface area is 
Step-by-step explanation:
The given net is made up of a rectangle and two circles.
The total surface area is the area of the rectangle plus the area of the two circles.
This implies that:
The rectangular surface can be folded into the curved surface of a cylinder with the two circles becoming the lid.
Answer:
A. One solution
Step-by-step explanation:
A. One solution
The answer is -3
If f(θ) = a cos(bθ), then from the first condition we find
f(0) = 3 ⇒ a cos(0) = 3 ⇒ a = 3
Together with the other conditions, it's evident that f(θ) has a period of π, so
2π/b = π ⇒ b = 2
so that
f(θ) = 3 cos(2θ)
