radius = D/2 = 7.7/2 = 3.85 cm
circumference = 2πr
= 2*22/7*3.85
= 169.4/7
= 24.2 cm
circumference = 2πr
= 2*22/7*3.85
= 169.4/7
= 24.2 cm

Step-by-step explanation:
Diameter = 7.7 (given)
Radius = 7.7 ÷2
= 3.85
Formula for area of circle = πr²
Then, the area is..
Area = πr²
= 3.14 × 3.85²
= 46.57²
Therefore the area is 46.57².
