**Cross-sectional area of a fire hose Math Central**

If you want to determine the square feet of a circle, you want to get the area. There are two formulas, in terms of diameter and in terms of radius. There are two formulas, in terms of â€¦... Find square footage of a 13' diameter circle?

**Polygons Area of polygons and circles - In Depth**

This means when you measure the radius of your circle, you need to convert the radius to feet. For instance if your radius measures 9 inches, you convert from inches to feet by dividing the radius by 12 because there are 12 inches in a foot. So your radius measurement of 9 inches equals .75 feet....A= The cross-sectional area of the conduit in square feet (ft2). So if you have a 5 inch hose how do they get A=0.136 ft2 ? And I know the velocity already v= velocity in ft per second. So if you have a 5 inch hose how do they get A=0.136 ft2 ?

**How do I find the square footage of a 13' diameter circle**

Measure the length and the width of your area in feet. Multiply the two numbers together. Total is the square footage required. Example: 25â€™ x 25â€™ = 625 sq. ft. How to calculate the area of a circle To calculate the sq. ft. of a circle, multiply the radius by the radius, then multiply by 3.14 how to fix a glitching screen The area of a circle equals pi (3.1415926...) times the radius squared, or pi(r2). So if the distance from the center of the circle to the edge is 2 feet, you would multiply 2 by 2, and then. How to find out the outside diameter of a circle

## How To Get Sq Feet Of A Circle

### A rectangular area measuring 80 ft by 60 ft equals 4800 square feet: Circular Areas. The area of a circle is determined by using the equation r 2, or 3.14 x the squared radius of the circle: Area = 3.14 x r 2. A circular flower bed measuring 40 ft in diameter would have a radius of 20 ft, so: Area = 3.14 x 20 2 = 3.14 x (20 ft x 20 ft) = 1,256 ft 2. Irregular Areas. Irregularly shaped

- Find square footage of a 13' diameter circle?
- Circular Areas / Square Footage. For circular areas you only need one measurement, the distance across the circle, or diameter (as shown in the image at the right). The formula then is: Area = (Diameter / 2) 2 x 3.14. Diameter in Feet Total Square Feet. Oval Areas / Square Footage. Oval areas need measurements similar to a rectangle. Simply take the length from one end to the other, and the
- How many square meters ( m 2 , sq m ) are in 1 circle 1-meter diameter ( 1 âˆ… 1 m )? How much of surface area from âˆ… 1-meter circles to square meters, âˆ… 1 m to m 2 , sq m? Exchange values and measures from one surface area unit to another unit by quick calculation.
- The circle that forms the floor has a radius of 2.5 feet and hence its area is Ï€ Ã— 2.5 2 = 19.6 square feet. To find the area of the wall imagine that it is lined with a large sheet of â€¦
