What is circumference of a 30 circle?
94.25 centimeters
Answer: The circumference of a circle with a diameter of 30 centimeters would be 94.25 centimeters.
How many feet are in a radius?
Divide the circumference by 2π to find the radius. For example, the circumference is 60 feet. Dividing 60 by 2π equals 9.549. The radius is 9.549 feet.
How do I calculate my feet round?
So if the diameter of your circle is 10 feet, you’d calculate:
- 10 × 3.14 = 31.4 feet 10 × 3.14 = 31.4 \text{ feet} 10×3. 14=31.
- 10 × 3.1416 = 31.416 feet 10 × 3.1416 = 31.416 \text{ feet} 10×3.
- 6 × 3.14 = 18.84 feet 6 × 3.14 = 18.84 \text{ feet} 6×3.
- 6 × 3.1416 = 18.8496 feet 6 × 3.1416 = 18.8496 \text{ feet} 6×3.
What is the area of a 30 diameter circle?
The area of the circle is 706.9 cm2 .
How many inches is a 30 circle?
94.24 inches
being D the diameter of the circle, in this case the wheel. Circ. = 30X∏ = 94.24 inches.
How do we find the radius of a circle?
Let us use these formulas to find the radius of a circle.
- When the diameter is known, the formula for the radius of a circle is: Radius = Diameter / 2.
- When the circumference is known, the formula for the radius is: Radius = Circumference / 2π
How long is a 30 inch circle?
How do I measure a circle?
Measuring the distance around the outside of a circle can be difficult, especially if you don’t have a flexible measuring tape. It is often easier to measure the diameter and multiply by 3.14. The formula is: circumference = pi times the diameter.
How to calculate the square footage of a circle?
The diameter should be measured in feet (ft) for square footage calculations and if needed, converted to inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m). The formula: Area of a Circle = π x (Diameter/2)^2. π = 3.142.
Is the diameter of a circle twice the radius?
Essentially, the diameter is twice the radius – or any line that goes from one side of the circle to the other while crossing its center. The circumference of a circle, however, is not that commonly understood by many.
How is the circumference of a circle measured?
Perhaps, their main variable is the radius – which is measured from the center of the circle to any of its sides. Essentially, the diameter is twice the radius – or any line that goes from one side of the circle to the other while crossing its center. The circumference of a circle, however, is not that commonly understood by many.
