Radius = Diameter/2
= 10/2 = 5 cm
Circumference if circle = 2πr
= 2 × 3.14 × 5
= 31.4 cm
Area of circle = πr^2
= 3.14 × 5 × 5
= 78.5 sq. cm

Step-by-step explanation:
Diameter of Circle = 10 cm
Radius = 5 cm
Area of Circle = πr² = 3.14 × 5 × 5 = 78.5 cm²
Circumference of Circle = 2πr = 2 × 3.14 × 5 = 31.4 cm
Area of Circle = 78.5 cm²
