Answer 1

a-b) 2,12 cm

c-d) 0,46 cm

e-f) 108 cm

g-h) 19,4 cm

i-j) 156 cm

Explanation:

The diameter of a circle is twice the radius:

a-b)

r = 1,06 cm

d = 2 × 1,06 = 2,12 cm

.

c-d)

r = 0,23 cm

d = 2 × 0,23 = 0,46 cm

.

e-f)

r = 54 cm

d = 2 × 54 = 108 cm

.

g-h)

r = 9,7 cm

d = 2 × 9,7 = 19,4 cm

.

i-j)

r = 78 cm

d = 2 × 78 = 156 cm
