What is the ratio of volume of a cone to the volume of a cylinder with same ratio?
It is 3:1. This is because volume of a cone is pi/3*r*r*h while vol of a cylinder is pi*r*r*h.
What classification of numbers does pi fit into?
pi is infinite pi is about 3.1415
If you have a cake recipe that is 6 inches in diameter and 2 inches high but you pour the batter into a round cake pan that is 8 inches in diameter how tall will the cake be?
The volume of the batter is the same. Volume in the 6 in pan: Pi r2 h = 18Pi . Volume in the 8 in pan: 16hPi . Equating the two: 18Pi = 16hPi gives h = 9/8 in.
Will the sum of two irrational numbers always be rational?
Consider pi and 4 - pi. 4 - pi + pi = 4, which is clearly rational. However, both pi and 4 - pi are irrational, as you can verify. plz to be lerning numburs Then consider pi + pi = 2pi, which is clearly irrational. The sum of two irrational numbers, therefore, may or may not be rational.
Why is pi a rational number?
Pi is irrational.
How do you find the radius of a cylinder using volume and height?
Volume = pi x r^2, so r^2 = volume/ pi r = sq root(volume/pi).
How much water does it take to fill a twenty four inch pipe by one foot long?
Assuming cylinder: volume = area of circle * length area of circle = pi*radius**2 radius = circumference/(2*pi) radius = diameter/2 if 24 inch is circumference: volume = pi*(24/(2*pi))**2 * 12 volume = 144/pi*12 volume = 1728/pi inch**3 if 24 inch is diameter: volume = pi*(24/2)**2 * 12 volume = pi*144*12 volume = pi*1728 inch**3 if 24 inch is radius: volume = pi*24**2 * 12 volume = pi*576*12 volume = pi*6912 inch**3 if 24 in
How do you find the volume for circular cylinder?
Volume = (Pi/4) * diameter2 * height or volume = Pi * radius2 * height
What is the volume of a sphere with a radius of 15cm?
Volume = 4/3*pi*153 Volume = 4500*pi cubic cm
What is the volume of this cylinder with a 3in side length and a 5cm radius?
Volume = pi*r2*h = 92.76 cm3 Volume = pi*r2*h = 92.76 cm3 Volume = pi*r2*h = 92.76 cm3 Volume = pi*r2*h = 92.76 cm3
What is the approximate volume of pi?
You calculate the volume of three-dimensional figures, not of numbers like pi.
What is the volume of the sphere with a radius of 12?
Volume is 4/3 x "pi" x r3 or 4(pi)r3 divided by 3. Volume=7234.56 when pi is 3.14
How many cubic feet in a cylinder 7 in diameter and 26 feet long?
area = pi*r**2 area = pi*(7/12)**2 volume = pi (7/12)**2*26 volume = pi (49/144)*26 volume = pi (49/72)*13 volume = pi 637/72
What are some formulas that include pi?
Area of a circle = pi*r2 Circumference of a circle = 2*pi*r or pi*d Volume of a sphere = 4/3*pi*r3 Surface area of a sphere = 4*pi*r2 Volume of a cone = 1/3*pi*r2*height Volume of a cylinder = pi*r2*height
How do you find Volume for a cylinder?
Volume of a cylinder = pi*(radius)2*(height) where pi = 22/7
How do you find the height of a cylinder when radious and volume are given?
pi*radius2*height = volume of a cylinder height = volume divided by pi*radius2
What is the volume of a sphere with a radius of 21 cm?
Volume of a sphere = 4/3*pi*radius3 Volume = 12348*pi cubic cm
