| What is the area of the circle with a circumference of 24 ft? [Use π = 3.14]
2 Circumference of the circle, 2 x π x r = 2 x 3.14 x r = 24
[Divide each side by (2 x 3.14)]
3 r = 242x3.14
6 = 3.82 ft
7 Area of the circle = πr2 = 3.14 x 3.82 x | Circumference of the circle = 24 ft
2 x π x r = 2 x 3.14 x r = 24
[Divide each side by (2 x 3.14)]
3 r = 242x3.14
6 = 3.82 ft
Area of the circle = πr2 = 3.14 x 3.82 x 3.82
[Substitute r = 3.82]
8 = 45.82 ft2
The area of the circle is |
