area = 3.14 x 7 x 7 / 4 = 38.465 square inches
a diameter for a circle possibly a bisector for other shapes
circumference formula is pi(diameter) diameter is 2(radius) radis=4; diameter=2(4)=8 pi(8)=circumference of the circle...this is the EXACT answer plug it into a calculator and you will get 25.1327412287 your welcome ;)
A circle with a radius of 11.64 meters has an area of 425.653131998 square meters.
To find the circumfrance of a circle, you need to multiply 2 times pi, times the circle's radius. If you don't know what that is, you multiply two times pi, and pi equals 3.14, and then multiply that by the radius, which is the measurement of half the circl'e diameter. the diameter is the distance from one side of the circle, to the exact opposite. you measure this with a ruler. HALF the measurement of the diameter is the radius. Example---the diameter of a circle is 20 cm. half the diameter is 10 cm, which is the radius. Multiply 2 times pi[which equals 3.14], times the radius. Good luck!
Exact area of the circle: 9*pi inches
Exact area of the circle: 9*pi inches
6.25PI
It is: 12.25*pi square units
There is no exact answer it depends on the circle. It is however you make it.
12.56637 square inches.
The diameter of a circle is the length of a straight line that goes through the exact center of a circle. The radius of a circle is the length of a straight line that starts at the exact center and reaches the circle. The radius is half the length of the diameter.
It is a diameter, the line that cuts the circle in an exact half.It is the diameter and passes through the center of the circle.
The diameter would be approximately 7. In exact figures it would be 7
area = 3.14 x 7 x 7 / 4 = 38.465 square inches
the exact circumference is 11pi inches
