Answer:

Step-by-step explanation:

To find the radius simply divide the diameter by 2

  • Radius = 2.4 cm
  • Diameter = 4.8cm

To find the circumference of a circle multiply the diameter by π or 3.14

  • Circumference = 15.072

To find the area of a circle use the formula A=πr2

A = π x 2.42 = 18.1

  • Area = 18.1
