ANSWER

A metallic pipe of 0.7 CM thick inner radius of the pipe is 3.5 cm and length is 5 cm find the total surface area

Posted by Ayush Ranjan 7 years, 2 months ago

CBSE > Class 08 > Mathematics

1 answers

Gaurav Seth 7 years, 2 months ago

Given,

Thickness of the pipe = 0.7cm

inner radius of the pipe (r )= 3.5cm

External radius of the pipe (R ) = (3.5+ 0.7)cm or,4.2cm

length=5dm or,50cm

We know,

Total surface area of pipe = 2π (r+ R ) ( h+ R - r)

or, Total surface area of pipe= 2×22/7(3.5+4.2)(50+4.2-3.5)

= 44/7 × 7.7 × 50.7

=2453.88cm²

So the answer should be 2453.88cm²
