What is the height of a cylinder?
The height of a cylinder all depends on what cylinder you are talking about. There is only an exact height if you have measured it yourself or someone has already measured it for you.
What is the exact area of a circle having a radius 6 in?
The formula for the area of a circle is pi times the radius squared, so if the radius is 6 inches, that is pi times 36 square inches. Pi is approximately 3.1415, which gives us an area of 113.094 square inches. If that is not exact enough, pi has been worked out to thousands of decimal places, and can be easily looked up on google.
How do you find the circumfernece of a circle?
If you want an approximate answer, you can measure it with string. If you want an exact answer and know the radius, multiply by 2*pi to find the circumference.
If the volume of a cube is 25 what is its surface area?
Your problem is quite easy...Since getting the volume of a cube is s3 we will do the opposite of it will get its cube root* First get the cube root of 25 = 2.9 (I just round it off but the exact measure is 2.924017738) * Then use the formula 6s2 for solving the surface area SA = (6)(2.9)2= (6)(8.41)SA = 50.46
Find the equation of a circle if the circle is tangent to the line -x y40 and the center is on the line x 2y30?
The equation of a circle is equal to: (x - a)2 + (y - b)2 = r2 Where (a, b) is equal to the center of the circle and r = radius. To understand more why this is the equation of a circle, think of a circle with a known center point (a,b). A circle, by definition, is the set of all points an equal distance from a given point (the center). That distance is also known as the radius. So if only we had some formula to calculate the radius, we would have our equation. Luckily we do. In your circle, imagine a right triangle with the hypotenuse being the radius (wikipedia has a good picture of this at http://en.wikipedia.org/wiki/Circle). Using the pythagorean theorem we have a formula for calculating the radius. Remember that the theorem states that: a2 + b2 = c2 Where a and b are the lengths of the two sides of the right triange adjacent to the right angle and c is the hypotenuse. For a circle with a center point at the origin, the length of the two sides a and b are simply x and y; howver if the center is not at the origin the length of each adjacent side is (x-a) and (y-b) (again draw the circle and triangle out or refer to the wikipedia drawing to better see this). Since c = radius, we now can substitute in and get: (x - a)2 + (y - b)2 = r2 Which we know is the equation of a circle In this problem, we don't know the exact center point or radius yet, we only know the equations of lines that intersect the center and are tangent to the circle. From my memory, this problem needs at least one more piece of information (the radius) before it can be solved. If someone else knows how to do this without the radius, please have at it; otherwise (to the poster) double check to make sure the problem you have did not specify a radius.
What is the formula for a volume of a cylender?
The formula for working out a cylinder is... pie radius squared times height The pie radius squared works out the area of one of the circle faces, and then multiplying it by the height sort of stretches out the circle face to the cylinder's exact volume
The volume of a right circular cylinder can be approximated as follows Volume and pir2h where r is the radius of the cylinder and h is the height of the cylinder and pi is a constant that is roughly e?
First, it is not an approximation but the formula for the exact value of the volume. Second, pi and e are quite different numbers.
Can you find the exact measurement of a cylinder?
What do you mean by "exact measurement"? Do you wish to determine the cylinder's height? Its diameter? Its surface area? Its volume?
What is the exact volume of a cylinder that has a base of 12mm and the height is 24mm?
Exact is difficult but it is approximately 2.713 cc.
What is the volume of the right circular cylinnder with a height of 12cm and a radius of 9cm?
A formula for the volume of a cylinder is 2 X pi X r2 X h, where r is the radius and h is the height. This formula yields about 3053.628059 cubic centimeters if the integers specified are considered exact or 3.1 X 103 cubic centimeters to the justified number of significant digits otherwise.
Find the exact volume of a cone that has a slant height of 26 inches and a radius of 24 inches.?
V = 6,032 cubic inches.
What is the height of a cylinder?
The height of a cylinder all depends on what cylinder you are talking about. There is only an exact height if you have measured it yourself or someone has already measured it for you.
How do you find the height of a can if the radius is 4cm and it is a 400mL can in the shape of a cylinder with an exact answer?
Volume of a cylinder = {pi}r2h. 1 litre = 1000cm3 so 1ml = 1cm3, thus 400ml = 400cm3 400cm3 = {pi}(4cm)2h h = 400cm3/({pi}16cm2) h = 25/{pi} cm As an exact answer is required, leave it in this form instead of dividing through (to get about 7.96cm).
What is the formula for determining the volume of a cylinder in gallons?
Cylinder volume in gallons = (pi) x (radius of the end in inches)2 x (length in inches) / (231) or (pi) x (radius of the end in feet)2 x (length in feet) x (7.48) . The first result is exact. The second result is short by 0.007% .
Is a meaturing cup the same as a a graduated cylinder?
No, it will differ.We can not take the exact volume in the measuring cup but measuring cylinder ll give you the exact volume .
Why can you find the exact surface area measurement for a prism and pyramid but not cylinder?
Because of the cylinder's circular shape, its surface area includes a multiple of pi. Because pi is an irrational number, you can not express its exact value numerically. The fact that you can't express it numerically does not however mean that you can't express it at all. For example, a cylinder with a radius of 1 centimeter and a height of 1 centimeter will have a surface area of exactly 4π centimeters.
What is the volume in cubic feet of a cylinder with a diameter of 1 foot and height of 3 feet?
To find the volume of a cylinder, first you find the area of the circular base. The area of the circular base is pi * r2, which in this case is: .5 * .5 * pi = .25pi Then you multiply that by the height of the cylinder: .25pi * 3 = .75pi cubic feet That is the exact answer, the approximate answer is .75 * 3.141593 = 2.356 cubic feet
