Radius = D/2 = 1.25 ft
Area = pi R2 = 1.5625 pi = 4.909 square feet (rounded)

What is the space inside a circle?
Circumference is the outside of the circle and the inside is the are of the circle. And inside of the circle, there is diameter and radius. Radius is from the center point to the edge of the circle and diameter is all the way across.
What is the inside diameter of a hydraulic tube with the outside diameter of 1 inch?
Less than an inch.
How do you find the circumference of a pipe?
Measure the inside diameter and multiply it by 3.14159 (pi)
If a circle has the diameter of 30 feet what is the largest square that can fit inside?
21.21 feet
How many gallons per foot for 16 inch pipe?
10.4448, assuming 16" inside diameter. 16" outside diameter would be slightly less.
Is EMT called by it inside diameter or outside diameter?
inside
How thick is a 24 reinforced concrete pipe?
30-inch (inside diameter) RCP has a wall thickness of 2.75 inches. Therefore, the outside diameter of 30-inch RCP is 35.5 inches.
How do you compute the square footage inside a circle?
Multiply the diameter by 3.1415 NO - ignore that! Diameter x pi (3.1416) is the circumference, the distance around a circle. Square footage is area, so the correct formula is Area = 3.1416 times radius squared. The radius would be measured in feet.
How do you compute area inside a circle?
3.14 X Radius Squared ?
What is the diameter of a pipe?
The diameter of a pipe is its width across an open end of the pipe. The inside diameter is the width measuring on the inside of the pipe; the outside diameter is the width measuring on the outside.______________________________________________________________________________________________________For a pipe of circular cross section, its nominal diameter is the diameter of the cross section.The inner diameter is the measuring on the inside of the pipeThe outside diameter is the measuring on the outside of the pipe.
How thick is the 25 inches reinforced concrete pipe?
1/12th inside diameter plus 1 inch for 'B' wall (most common type), additionally, pipe sizes are normally in 1/4 or 1/2 foot increments, so the closest size would be a 24 inch diameter with 3 inch wall (24/12=2+1=3) having a outside barrel diameter thickness of 30 inches for 'A' wall 1/12th inside diameter, 'C' wall is 1/12th inside diameter plus 1 3/4 inch
What is the inside diameter of 0.75 inch pipe?
Three-quarter inch diameter pipe refers to the outside diameter. Different pipe types of the same outside diameter usually have different inside diameters. ASTM SCH 40 pipe of 3/4 inch diameter has an inside diameter of 0.824 inches. ASTM CL 200 pipe of 3/4 inch diameter has an inside diameter of 0.930 inches because of the thinner wall.
Do you use inside diameter or outside diameter when calculating the area of a pipe?
When dealing with pipe the volume is more important, therefore, I would use the inside diameter.
How do you make reinforced concrete?
Reinforced concrete is just normal concrete with steel reinforement placed inside.
Why concrete bridges have steel rods inside them?
The steel rods are there to strengthen the concrete - making it reinforced concrete.
How do you strengthen concrete?
you could strengthen it by putting metal bars inside the concrete
