Welcome to Catalytic, a blog to discuss the discussion of subject matter from Higher Education, High School, Middle School and Elementary Schools. This time Katalistiwa will discuss a question that is often asked in school exams. The questions are: **The formula for calculating the area of a tube blanket**

cylinder cover area = 2 x π xrxt

or

cylinder cover area = π xdxt

### Detailed discussion of Tube Covers

Tube ie Wake up space with curved sides

**The formulas that exist in the wake of the tube**

1) area of the cylinder base = π x r²

2) tube cover area = 2 x π xrxt

or = π xdxt

3) surface area of tube without lid = area of base + area of blanket

= π x r² + 2 x π xrxt

= π xrx (r + 2t)

4) surface area of tube with lid = area of base + area of lid + area of blanket

=π x r² + π x r² + 2 x π xrxt

= 2 x π x r² + 2 x π xrxt

=2 x π xrx (r + t)

5) cylinder volume = π x r² xt

r = radius

d = diameters

t = height
