It seems like there's an error in your question. Circumference (of a circle) = pi * diameter. You can approximate pi with the fraction 22/7, then Circumference = (22/7)*49 = 154
If the circumference of a circle is 44 inches, the area is: 154 square inches.
Area = pi*72 = 153.93804 or about 154 square units
It is 14.00281721 or about 14 cm
pi*radius2 = 154 sq cm radius = 7.001408606 cm circumference = 2*7.001408606*pi = 43.99114768 or about 44 cm
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.

If the circumference of a circle is 44 inches, the area is: 154 square inches.
diameter = 43.98226/pi = 13.99998817 radius = 13.99998817/2 = 6.999994087 area = pi*6.9999940872 = 153.93778 or about 154 square units
Radius of circle: 44/2*pi = 7 rounded Area of circle: pi*7 squared = 154 square cm rounded
154 square inches.
Area = pi*72 = 153.93804 or about 154 square units
pi*72 = 153.93804 or about 154 square cm
It is 14.00281721 or about 14 cm
Radius of circle is the square root of 154/pi = 7 units rounded
Radius of circle: 44/(2*pi) = 7 cm rounded Area of circle: pi*7^2 = 154 square cm rounded
