First divide the diameter by 2, to get the radius. Then use the formula area = pi x radius2.
The area of a circle with a 7-foot diameter is: 38.48 square feet.
The circumference is about 22 units.
Diameter = Radius*2 = 14 units. Circumference = pi*Diameter = 43.98 units.
If you mean area of a circle then it is: pi times 3.5 squared = 38.485 square units rounded to 3 decimal places
First divide the diameter by 2, to get the radius. Then use the formula area = pi x radius2.
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.
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 radius of a circle is half the diameter.
The circumference is about 22 units.
Diameter = Radius*2 = 14 units. Circumference = pi*Diameter = 43.98 units.
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 is approx 2.23 units of length.
Circumference of a circle = 2*pi*radius or pi*diameter 7*pi = 21.99114849 units Therefore the circumference ot the circle is 22 units correct to the nearest unit.
A circle with a 7 inch diameter has an area of 38.48451.
A 7-meter diameter circle has an area of 38.5 square meters.
