Question

50.27 cm of string was needed to wrap around a circular object twice. What is the radius of the object?

Answer 1

Step-by-step explanation:

Given :-

• perimeter of circle = 50.27

Solution :-

• perimeter of circle =
• $2\pi \: r$

$2\pi \: r = 50.27 \\ \\ 2 \times \frac{22}{7} \times r = 50.27 \\ \\ 44 \times r = 351.89 \\ \\ r = 7.7749$

Hence,Radius r is 7.7cm
