Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2

How do you calculate the square footage of a round tank?
you use the formula: Pi x radius (half the diameter) squared.
How do you draw an X in a square with half circles around the square?
yeah you draw the left half circle first, and at the bottom of the half circle you draw a line (long enough to later fit a square) and connect it to another half circle, which connects back to the top. so now you sort of have a square, but with two sides being half circles. starting on where you were left from the half circle, go down diagonal to make one of the lines in the x, go up to make a side of the square, and then diagonal down the other direction to make the x. then continue by going up and finishing the square. that is possible to do without lifting your pen, or retracing your lines. it might sound confusing here, but i tried to explain it best as possible! good luck (:
How do you calculate the radius from the circumference?
Of a circle: divide the length of the circumference by the value of Pi (about 3.14159). The answer is the diameter. Half of the diameter is the radius
How many square feet in a circle that is 52 feet in diameter?
The formula for the area of a circle is pi (3.141265...) times the radius squared. Since half of the diameter is the radius, plug that number into the formula to get the total square feet.
What is half of a diameter of a circle?
The radius is half of the diameter of a circle.
How do you estimate square footage?
Square footage is the length of your room times the width. For a circular room, measure the diameter (length across the circle), divide by 2 to get the radius (length across half the circle), multiply by pi and square it. The formula for the area of a circle is πr^2, and Pi (π)= 3.1416
How do you calculate the square footage of a round tank?
you use the formula: Pi x radius (half the diameter) squared.
How do you calculate square foot of semi circle?
You take half the area of a circle in square feet. The formula is: 1/2 * pi * (radius)2
What is the formula for square footage of a triangle?
Treat it as a square and half the result.
How do you find the square footage of a round room?
the area of a circle is pi times the radius squared, the radius being half the diameter. Pi is approximately 3.14
How do you find the radius of a circle inside a square?
The same as half the side of the square, as the radius of the circle is half its diameter, and the diameter of the circle is equal to the side of the square.
How do you calculate the radius of a circle?
The radius of a circle is half of its diameter.
The length of your garden is 11 feet by 6 feet at it maxium width you are attempting to make a half circle garden how would you figure out square footage?
Assuming your aim is the largest semicircle within the rectangular area, it would be a half circle of radius 5.5 ft. A circle's area is Pi times the radius squared, so the half circle would be 1/2 * 3.14 * 5.5 * 5.5 , which equal 47.5 square feet.
How do you calculate half of a circle if the radius is 6 centimeters?
The answer depends on what characteristic of a half circle you want to calculate: its area or perimeter or something else.
What is the square footage of 20 feet x 3 and half feet?
70 square foot.
How do you find circumferince of half a circle?
You calculate the circumference of an entire circle, then divide by 2.
How do you find the radius of an inscribed circle of a square given the area of the square?
Half the square root of the square radius equals the circle radius.
