The formula for the surface area of a cylinder is:
SA = 2πr² + 2πrh
where r is the radius of the base and h is the height of the cylinder.
First, we need to find the radius of the cylinder. We know that the diameter is 10 inches, so the radius is half of that:
r = 10 / 2 = 5 inches
Now we can plug in the values for r and h into the formula:
SA = 2π(5)² + 2π(5)(25)
SA = 2π(25) + 2π(125)
SA = 50π + 250π
SA = 300π
So the surface area of the cylinder is approximately 942.48 square inches (if we use π ≈ 3.14159).
What is the surface area of the cylinder?
Diameter: 10 inches
Height: 25 inches

is it normal to have dreams everyday? I've been having dreams like every single day
It is completely normal to have dreams every day. In fact, most people have several dreams each night, even if they do not remember them. Dreams are a normal part of the sleep cycle and are believed to serve important purposes, such as processing emotions, consolidating memories, and problem-solving. It is not unusual to go through periods where dreams are particularly vivid or frequent, but if you are experiencing distressing or disturbing dreams that are impacting your daily life, it may be helpful to speak with a healthcare provider or mental health professional.
