If the object is a circle and if 24 is the diameter, the area is 452.39 and the circumference is 75.4
The circumference is 24*Pi yards.The surface area = circumference x heightthereforeheight = surface area / circumference = 1206 sq.yd. / 24*Pi yd. = 15.9951 yards or 16 yards (rounded).
you divide the surface area by the circumference.
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
If the object is a circle and if 9.5 is the diameter, the area is 70.88 and the circumference is 29.85
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Circumference = 2*radius Area = 2*pi*radius2 Area = 2*pi*(circumference/2)2
Circumfrences are only for circles.
The Perimeter of a circle is it's circumference. And the circumference is the diameter times pi. So to find the area, divide the circumference by pi, and get the diameter. Then divide the diameter by 2, to get the radius. Then multiply the radius times itself, and multiply that by pi.
To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
If a circle has a diameter of 24 inches its circumference is: 75.4 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
The area of a circle is (pi x radius squared) A = πr2 The circumference is (pi x diameter) C = π (2r) So if you have the circumference, the area is the circumference squared, divided by 4pi (about 12.566). A = C2/4π Example: A circle with a diameter of 6 inches has a radius of 3 inches Area A = pi (32) or about 28.27 square inches Circumference C = pi (6) or about 18.85 inches Using C2/4pi, the area is 18.85 x 18.85 / 12.566 = about 28.27 square inches
Divide the circumference by pi, divide the result by 4, and finally, multiply the result by the original circumference. Ex. The circumference of a circle is 43.96 units long. What is the area of the circle? (use 3.14 as pi). Solution: First, divide 43.96 by pi, which is 3.14 in this question. The result should be 14. Next, divide 14 by 4,getting 3.5. Finally, multiply 3.5 by the original circumference, which was 43.96, and the final result should be 153.86. The answer to the example is 153.86 square units.
fu
Diameter = Circumference/pi
If the area is a circle, the circumference is 0.28 miles.
Okay finding circumference from knowing the radius right? The radius is equal to half the diameter and circumference is equal to pi * diameter. So double the radius and multiply it by 3.14 then you will get the circumference!
