Answer:
Area of circle = 62.459624 square cm .
Step-by-step explanation:
Given: circumference measures 28 centimeters.
To find : Find the area of a circle .
Solution : We have given
circumference =28 cm
circumference = 2 *pi * radius .
Plug the value of circumference = 28 cm , pi = 3.14
28 cm = 2 * 3.14 * radius .
28 = 6.28 * radius.
On dividing both sides by 6. 28
Radius = 4. 46 cm
Area of circle = pi (radius )².
Area of circle = 3.14 ( 4.46)².
Area of circle = 62.459624 square cm .
Therefore, Area of circle = 62.459624 square cm .
