Answer 1

$\huge\mathcal\colorbox{pink}{{\color{b}\huge\purple{➳Answer}}}$

Circumference of circle = 2πr

616 = 2 × 22/7 × r

616 × 1/2 × 7/22 = r

98 = r

Therefore, radius is 98cm

Answer 2

Answer:

98cm

Step-by-step explanation:

$2\pi \: r \: = circumference \: of \: circle$

2 * 22/7 * r = 616

44 * r = 616 * 7

44 * r = 4312

r = 4312/44

r = 98
