Formula for finding circumference is Pi (3.14) X diameter, so 12 yds times 3.14 = yds.
Formula for area is Pi (3.14) x radius (1/2 the diameter=6) squared. So the radius squared is 6 X 6 = 36, X 3.14. You can do the math! Area will be in square yds.
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference. If they said "What is the circumference if the area of a circle is 36pi?" Area of a circle is pi*r2, which would give us a value for r = 6 Diameter is 2*r, or = 12. Circumference is d*pi, or 12pi
circumference = π x diameter ⇒ diameter = circumference ÷ π = 12 cm ÷ π ~= 3.8 cm
The circumference and area of a circle with diameter of 12 inches are:C = 37.7 inchesA = 113.1 square inches
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or pi*diameter
The circumference of a circle with a diameter of 12 is about: 37.7 (C = diameter x Pi).
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
The circumference of a circle with a diameter of 12 cm is: about 37.7 cm
Area = pi*62 Circumference = pi*12 or 2*pi*6
They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference. If they said "What is the circumference if the area of a circle is 36pi?" Area of a circle is pi*r2, which would give us a value for r = 6 Diameter is 2*r, or = 12. Circumference is d*pi, or 12pi
For the small circle of diameter 6, the circumference is 18.84.
The diameter of a circle with a circumference of 12 is: about 3.82To to this calculation for other circles, just divide the circumference by Pi (about 3.1416). The result is the diameter.
The circumference of a circle is pi times the diameter, so it would be 12*pi or about 37.7.
