Question

circumference of the circle diameter equals to 50 cm​

Answer 1

Step-by-step explanation:

circumference formula is 2πr

r = 50 cm= 0.5 m

i.e, 2πr = 2 × 3.14 × 0.5

=3.14 metre

Answer 2

Answer:

157cm = 1.57m

Step-by-step explanation:

Diameter = 50cm

Radius = 50/2 = 25cm

Circumference of the circle = 2πr

Circumference of the circle = 2 × 3.14 × 25

Circumference of the circle = 50 × 3.14

Circumference of the circle = 157cm = 1.57m
