How many square feet in a 50 inch diameter circle?
Diameter = 50 inches Radius = 25 inches Area of circle = pi x 25 x 25 = 3.1415 x 625 = 1963.44 square inches which is equivalent to 1963.44/144 = 13.63 square feet
What is The circumference when the radius is 25 in?
THE FORMULA FOR FINDING THE CIRCUMFERENCE IS:CIRCUMFERENCE EQUALS DIAMETER TIMES 3.14In basic words:What do you know?You know you need to find the circumference of the circle, which is the distance all the way around the circle.You know the radius is 25 inches, the radius is the measurement from the center to the circumference of the circle.You know the formula needs the diameter, a diameter being the length of a line connecting two points on the circumference, touching the center of the circle, maintaining a straight line.With all this information, you can figure out that the radius is half the diameter.Now, begin your math.Problem: What is the circumference of a circle when you know the radius is 25 inches?Formula: Circumference= Diameter X 3.14 which is known as pi.Radius Diameter CircumferenceR=25 D=R times 2Replace variable R with the correct number:2525 multiplied by 2 is 50 which means that D=5050 multiplied by 3.14 is 157The circumference is 157
What size of sheet metal is required to fabricate a cylinder 20 inches long and 8 inches in diameter?
Circumference = pi * diameter = 3.141592654 * 8 = 25.133 inches So> 25.133 inches * 20 inches
What is the equation of a circle whose diameter's end points are at 2 -3 and 8 7?
The mid point of the diameter is the circle's centre: Mid point of (2, -3) and (8, 7) is ((2 + 8)/2, (-3 + 7)/2) = (5, 2) The radius is half the diameter, but as the equation for a circle requires the radius squared: radius = diameter/2 → radius² = diameter² / 4 Diameter (and diameter²) can be found using Pythagoras: diameter² = change_in_x² + change_in_y² = (8 - 2)² + (7 - -3)² = 6² + 10² = 136 → radius² = 136/4 = 34 Circle with centre (X, Y) and radius r has equation: (x - X)² + (y - Y)² = r² → (x - 5)² + (y - 2)² = 34 → x² -10x + 25 + y² - 4y + 4 = 34 → x² + y² - 10x - 4x - 5 = 0
What is the formula for calculating the capacity of a drinking straw?
A standard drinking straw is a cylinder. The formula for calculating the volume of a cylinder is: Pi x r2 x length. So, a drinking straw that is 9.5 inches long with a diameter of .25 inches (1/4 inch) has a volume calculated like this:Pi (3.1416) x radius squared (.1252 = 0.015625) x length (9.5) = 0.46633125 cubic inches
What is the radius of a 50 inches diameter circle?
Radius = 1/2 (diameter) = 25 inches.
If the diameter of a circle is 25 inches what is the radius?
12.5 inches
If the radius of a circle is 25 inches what is the diameter?
The answer is 50 inches.
How many square inches in a 25 diameter circle?
I'm not completely sure what a "2.5 inch circle" is. Is that the distance all the way across the circle (diameter), or is it the distance from the center of the circle to its curve (radius) ? If diameter = 2.5 inches, then area = 4.909 square inches If radius = 2.5 inches, then area = 19.635 square inches
What is the area in square inches of a circle with a diameter equal to 10 inches?
Area of a circle = (pi) x (radius)2 Radius = 1/2 the diameter = 5 inches Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)
What the area of the circle if diameter is 10 inches?
Radius is half diameter, ie 5". Area is pi times the square of the radius ie 3.14 x 25 which is 78.5 sqin.
What is the radius of a cylinder with a surface area of 7850 and diameter of 25?
If the diameter is 25 then the radius must be 12.5
What is the diameter of a circle if the radius is 12.5?
25. The answer also depends on the unit of measurement (feet, inches, centimeters, etc.)
How many square feet in a 50 inch diameter circle?
Diameter = 50 inches Radius = 25 inches Area of circle = pi x 25 x 25 = 3.1415 x 625 = 1963.44 square inches which is equivalent to 1963.44/144 = 13.63 square feet
what is the radius of a drum whose diameter is 50cm?
Radius = Diameter / 2 = 25 cm.
What is the circumference of a circle whose diameter is 25 inches?
The circumference of a circle with a radius of 12.5 is 78.54 to two decimal places.
What is the radius of a circle with a diameter of 25 cm?
Radius = 1/2 of the diameter = 12.5 cm.
