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 area of the tube blanket in the figure is**

753.6 = 3.14 × r² × 15

r² = 753.6 ÷ ( 15 × 3.14 )

r² = 16

r = 4 cm

**Wide** **Blanket**

= 2πrt

= 2×3.14×4×15

= 376.8 cm²

So the answer is

### Detailed discussion of Tube Covers
