​

Answer 1

Answer:

62.8 cm is the circumfrence and 20 cm is the diameter

Step-by-step explanation:

10 cm is radius so:-

10*2=20

and we find diameter

Answer 2

Answer:

diameter 20cm

circumference = 62.82 cm ( approx )

area = 314.15 cm2 ( approx)

Step-by-step explanation:

diameter = 2r = 2 x 10 = 20 cm

circumference = 2πr = 2x 3.141x 10 = 62.82cm

area = πr2 = 3.1415 x (10)2 = 314.15 cm2
