The radius of the circular pipe is 10 cm. What length of tape is required to wrap once around the pipe? (Take [tex] \pi = 3.14 [/tex])

A. 62.8 cm
B. 31.4 cm
C. 62 cm
D. 60 cm

Answer :

Final answer:

The length of tape needed to wrap once around a circular pipe with a radius of 10 cm is calculated using the formula for the circumference of a circle. Upon calculation, the required length is found to be 62.8 cm. So, the correct answer is Option A.

Explanation:

To find the length of tape required to wrap once around the pipe, we need to calculate the circumference of the pipe. The formula for the circumference of a circle is C = 2\(\pi\)r, where r is the radius of the circle. Since the radius of the pipe is given as 10 cm, we can plug this value into the formula and use \(\pi\) = 3.14 to get the circumference.

C = 2 * 3.14 * 10 cm = 62.8 cm

Therefore, the length of the tape required to wrap once around the pipe is 62.8 cm. So, the correct answer is Option A. 62.8 cm.
