If you mean the area of a circle then it is: pi times radius squared
Diameter of a circle is pi times the square of its radius. For a circle having a diameter of 7 mm, area = pi (3.1416) x 3.5 mm x 3.5 mm = 38.5 square millimeters.
Since the area of a circle is pi times the radius squared. The radius is 7. The diameter would be 14.
3.14 x 7 x 7 is the approximate area of a circle having a diameter of 14 units. The answer is 153.86 square units.
The general formula for the area of a circle is pi times the radius squared. The radius is half the diameter, so the area is pi times half the diameter times half the diameter again.
A circle with a diameter of 7 inches has an area of 38.48 square inches.
The area of a circle with a 7-foot diameter is: 38.48 square feet.
If you mean area of a circle then it is: pi times 3.5 squared = 38.485 square units rounded to 3 decimal places
It will be diameter times pi or 3.14 or 3
Well, you find the area of a circle by multiplying (pi times radius2) or (pi times radius times radius). The radius is half of the diameter. The formula for the circumference is (pi times diameter). Multiply the radius times 2 to get the diameter. Multiply the diameter times pi.
The surface area of a sphere with a diameter of 7cm is 153.9cm2
the answer is 21. the circomference is 3 times the diameter. so 7 times 3 = 21
The area of a circle is pie(22/7) or (3.14) times R2 R = the radius of the circle (1/2 of the diameter)
