Area of a circle is = Pi * Radius Squared.
Depending how accurate you want to be you might need a calculator for Pi to more places but using Pi = 3.14
3.14 * 7 * 7 = 153.86 you should supply some units. If the 7 was in m this answer is in m squared.
Circumference is generally = 2 * Pi * Radius
2 * 3.14 * 7 = 43.96 again if the 7 is in meters then the answer is in m.

What is the area of a circle if its circumference is 14π?
Circumference is 2π times the radius. So, for 14π the radius is 7. Area is πr2, so the area of a circle with radius 7 is 72π, or 49π (153.93).
How can you find area of a circle whose circumference is 44cm?
Radius of circle: 44/2*pi = 7 rounded Area of circle: pi*7 squared = 154 square cm rounded
What is the radius of a circle whose circumference is 43.96 inches?
The radius is 7 inches.
If the radius of a circle is 7 cm what is the circumference of the circle?
Circumference = 2 pi R = 14 pi = 43.9823 cm (rounded)
What is the circumference of a circle if the radius is .25 inches?
circumference=2*pi*r =2*(22/7)*0.25=1.57 inches
