How do you get he circumference of a circle?
To get the circumference of a circle first you have to find the diameter of the circle and multiply the diameter by Pi (3.14 in short). so it is the diameter * Pi.
How do you find the surface area of a circle?
you find the surface area of a circle by first finding the area of the circles/ two ends. you do this by multiplying the diameter by pi then multiply by two, that is both ends put together then you find the area of the flat part by finding out the circumference of the circle ends, then multiply that by the height of the cylinder. circumference= pi times the diameter then add all your calculation together, and you have the surface area of your cylinder :)
What is the diameter of a circle with an area of 2.6 square units?
The area of a circle is -(pi)r^2 = AWe can find the diameter by first finding the radius. First we plug in the information we already know.(pi)r^2 = 2.6Then we divide both sides by pi to isolate 'r'.r^2 = .83We take the square root of both sides.r = .91Since the diameter is twice the radius we multiply the radius by 2..91(2) = 1.82The diameter of the circle is 1.82 units.
How do you get the circumference of a circle if you have the radius?
Easy. First, double the radius to get the diameter. Next, multiply the diameter by pi (about 3.1416). The result is the circumference of the circle.
How do you find the area and perimeter of circle?
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
How do you find out the diameter when you have a circumference?
To get the diameter from the circumference of a circle, just divide by pi (which is 3.1415 to the first 5 digits).
How would the area of a circumerancebe affected when the diameter of a circle is doubled or triple?
First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
How do you discover pi?
First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide the circumference by the diameter.
How many inches is in 1 diameter?
The diameter of a circle is a straight line passing through the center of the circle and connecting two points on the circle. The length of the diameter is equal to twice the length of the radius of the circle. Since there are 2.54 centimeters in an inch, converting the diameter from inches to centimeters would involve multiplying the diameter in inches by 2.54.
What is the area of a circle if the diameter is 4.4cm?
Since the area of a circle can be represented by the equation A=πr², to find the are of a circle you merely need to fill in the variables. The radius is half of the diameter, so a circle with a diameter of 4.4 cm has a radius of 2.2 cm. A=π(2.2)². First, square 2.2 and you will get 4.84. Then, multiply 4.84 by pi and you will get approximately 15.2. The area of a circle with a diameter of 4.4 cm is approximately 15.2 square cm.
How do you convert the diameter of a circle to square Inches?
If you want the area of a circle, and you know the diameter, then: A = pi*r^2, where r is the radius, and is 1/2 the diameter, so pi*(diameter/2)^2 = (pi/4)*(diameter)^2. If you want square inches, then make sure you have the diameter measurement in inches, first.
What is the diameter of a circle with an area of 254 cm?
To find the diameter of a circle with an area of 254 cm², you first need to calculate the radius. The formula for the area of a circle is A = πr², where A is the area and r is the radius. So, 254 = πr². Solving for r gives you r ≈ √(254/π) ≈ 9 cm. The diameter of a circle is twice the radius, so the diameter of this circle is approximately 18 cm.
