How to Convert circumference into square meter?
circumference = diameter x pi area = radius squared times pi divide circ with pi gives you the diameter diameter/2 gives you radius radius times itself times pi gives you the area get the units right and you're done.
How do you convert diameter into radius?
Diameter is half of the radius. Times it by 2.
What happens to the area of a circle when the radius is doubled tripled?
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
How do you convert basic circumference into radius?
Circumference = 2*pi*radius Radius = Circumference/(2*pi)
How do you convert radius into perimeter?
Multiply the radius by itself, then multiply the result by Pi.
How do you convert diameter to area?
To convert diameter to area , you will need to divide the diameter by two so as to get the radius. The result you get, square it and them multiply it by 3.14 to find the area.
How do you convert radius miles into square miles?
To convert radius miles into square miles, you would need to use the formula for the area of a circle: A = πr^2, where r is the radius. Square the radius value, then multiply it by π (approximately 3.14) to get the area in square miles.
How do you convert an area of 16.5 acres into a distance around an island?
assuming the island is circular.... use the formula Area=(pi)x(radius squared) to find the radius, then use the formula C=2(pi)(radius) to determine the circumference.
If a cylindrical bar has a radius 2 m and height 9 cm and if it is melted and become asphere. What is the radius of spherea) 3b) 6c) 9d) None?
First find the area of the cylindrical bar or cylinder area = 2 · π · r · (r + h). Convert your measurements to the lesser of the two (cm is smaller than meters, so they both need to be cm). Plug your numbers into the formula and solve for area. Next, use a sphere area formula to solve for radius area = 4 · π · r2. Enter the area number you found from the first equation and solve for (r) or radius. Once you arrive at your answer (you need to practice math to learn it), you need to convert your measurement back to meters. Good luck!

How do you convert radius into circumference?
2 x pi x radius
How do you convert diameter into radius?

What happens to the area of a circle when the radius is triple?
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
How do you get circumference from area of a circle?
Area = π × radius² → radius² = area/π → radius = √(area/π) Circumference = 2 × π × radius = 2 × π × √(area/π) = √(2² × π² × area/π) = √(4 × π × area)
What happens to the area of a circle when the radius is doubled tripled?
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
How do you find the diameter of a circle if they give you the area?
Area = pi * (radius^2) Where (radius^2) is radius squared, or radius to the second power. do some algebraic steps: Area / pi = radius^2 radius^2 = Area / pi square root (radius^2) = square root (Area / pi) radius = (plus or minus) square root (Area / pi) If you are not working with imaginary numbers then radius = square root (Area / pi)
