Question

Find the area of a circle with a circumference of
6.28

Answer 1

Explanation:

Circumfernece of circle = 2πr

6.28 = 2πr

r = 6.28/2π

r = 1 unit

Area A = πr²

A = 3.14 × 1²

A = 3.14square unit

Answer 2

3.142

Explanation:

C = 2πr (circumference of a circle)

6.28 = 2πr

r = 6.28 / 2π

r = 6.28 / 2 * 3.142

r = 6.26 / 6.284

r = 0.996

r = 1 (approximately)

Let's solve for Area!

Area of a circle is :

A = πr^2

A = 3.241 * 1 ^2

A = 3.142 or π ( base on the option given in the question.
