Question

the radius of a circular pipe is 3.5cm. What is the length of the tape is required to wrap 4 times around the pipe

Answer 1

Answer:  The length of tape required is 88 cm

Step-by-step explanation:

Radius;r of circular pipe = 3.5 cm

As we know Circumference; C is given by

$C= 2\pi r = 2\times \dfrac{22}{7} \times 3.5= 22 cm$

therefore the tape required to wrap 4 times = 22 x 4 = 88cm

Hence, the length of tape required is 88 cm

Answer 2

Answer:

$\green { Length \: of \: tape \: required = 88\:cm}$

Step-by-step explanation:

$\blue { Radius \: of \:a \: circular \:pipe (r) = 3.5\:cm}$

$Length\: of \: the \: tape \: required \:to \\wrap \: 4 \: times \: around \: the \:pipe \\= 4 \times \orange { circumstance\:of \: the \: circle }$

$\boxed { \pink { C = 2 \pi r }}$

$= 4 \times 2 \times \left( \frac{22}{7}\right) \times 3.5 \: cm$

$= 4 \times2 \times 22 \times 0.5$

$= 4\times 22$

$= \green {88\: cm }$

Therefore.,

$\green { Length \: of \: tape \: required = 88\:cm}$
