The surface area formula you provided can be broken down into two parts:
for the top and bottom circular bases, and
for the curved surface area. Here, the radius
is
and the height
is
. The circumference of a circular base can be calculated using the formula
. So plugging in
, we get
.
The options you provided are all multiples of
, and understanding the different areas represented in geometry can get a bit confusing. It’s like a pizza: the circumference represents the crust, while the surface area represents the entire pizza, including the toppings! So, just remember—when it comes to circles, the circumference is all about that round edge!
