Question

surface area of a 4m long pipe with1/8m of its diameter is ​

Answer 1

Answer:-

Surface area = 1.57 sq.feet

Step - by - step explanation:-

Given:-

Diameter (d)= 1/8 m

Length of pipe= 4 m

Find :-

Surface area = ?

Solution:-

We know that ,

Surface area of a pipe = π × length × (d)

Hence,

$\bf{surface \: area \: = \pi \: \times 4 \times \frac{1}{8}} \\ \bf{ \because\: \pi = 3.14} \\ \\ \implies \: 3.14 \times 4 \times \frac{1}{8} \\ \\ \implies \: \frac{3.14}{2} \\ \\ \implies \: 1.57 \: \bf{square \: feet.}$

Surface area = 1.57 sq.feet
