Answer 1

Hey mate here is your answer:-

If length is 44cm.

Then we know that,

2πr = 44(use to solve the problems)

or, r = 44×7/22×1/2

or, r = 7cm

Hope, I helps you.....Make your future bright....

Answer 2

Given :

• θ = π /4 = 180 / 4 = 45°

• Length of arc = 44 cm

To Find :

• Radius of the circle

Solution :

$\large \boxed{ \tt \green{l = 2\pi r \times \frac{ \theta}{360}} } \\ \\ \tt \implies 44= 2 \times \frac{22}{7} \times r \times \frac{45}{360} \\ \\\tt \implies44 = \frac{44}{7} \times r \times \frac{1}{8} \\ \\ \tt \implies r = \cancel{44} \times \frac{7}{ \cancel{44}} \times 8 \\ \\ \tt \implies r = 7 \times 8 \\ \\ \large \implies \boxed{ \tt r = 56 \: cm}$
