Question

find the radii of circle if the circumference is 100 cm
use Pi = 3.14​

Answer 1

Answer:

15.9235

Step-by-step explanation:

we know the formula

2*pi*r = circumference

- 2 * 3.14 * r = 100cm

- r = 100/6.28 = 15.9235 cm

Answer 2

circumference of circle = 2πr

100 cm = 2 × 3.14 × r

100 = 6.28 × r

100 / 6.28 = r

15.92 cm  =r
