Answer 2

Answer:

220 cm

176 cm

154 cm

Step-by-step explanation:

circumference of the circle =2 π R

R = Radius = Diameter/2

=> Diameter = 2R

π = 22/7

=> circumference of the circle = 22 * Diameter / 7

Diameter = 70 cm

circumference of the circle =  22 * 70 / 7  = 220 cm

Diameter = 56 cm

circumference of the circle =  22 * 56 / 7  = 176 cm

Diameter = 49 cm

circumference of the circle =  22 * 49 / 7  = 154 cm
