How do you use pi to find a circle's dimensions?
Pi is defined as the ratio of the circumference of a circle to the diameter of the circle.Therefore, if you measure the diameter of the circle (call it 'D') then the circumference of the circle is pi times D.To find the area of the circle use the formula Area = pi* D2 /4 .Going one step further, to a sphere, if you measure the radius of the sphere (call it R, where R is half the diameter D), then:1) The surface area of the sphere is Area = 4 * pi * R2 .2) The volume of the sphere is Volume = (4/3) * pi * R3 .
Why is Pi important?
pi is important because you can use it to calculate the circumference of a circle. you can also find the volume of a sphere. pi is approximately equal to 3.14159, and it plays a large role in our education.
What is a A sphere whose volume in cubic centimeters is 400?
A sphere with this volume has a diameter of 9.1416 cm, a surface area of 262.54 square cm and a circumference of 28.719 cm.
What is the volume of a sphere with a radius of 3.1 mm?
124.788249 or 125 mm3 to the nearest cubic mm
What is the circumference of a sphere whose volume is 904.7786842 cubic cm?
First we have to find the radius of the sphere because the circumference is 2*pi*radius. 4/3*pi*radius3 = 904.7786842 cubic cm With your calculator multiply both sides by 3 and then divide both sides by 4*pi: radius3 = 216 Cube root both sides: radius = 6 cm Circumference = 2*pi*6 = 37.69911184 or 38 cm to the nearest cm.
Why is pi important in layman term?
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
Find the volume to the nearest tenth of a sphere with a circumference of 12 feet?
First we have to find the radius by dividing the circumference by 2*pi which works out as 1.909859317 feet Volume of a sphere = 4/3*pi*radius3 Volume = 29.18050088 or 29.2 cubic feet to the nearest tenth
How can pi help you measure?
Pi is not a size. Pi is usually 22/7. Sometimes also 3,14. Pi is used to measure area and circumference of a circle, and the volume of sphere / tube. If there is no pi, then the area and circumference of circle, and the volume of sphere / tube will not be counted.
What is pi used for in geometry?
Some of the many applications that pi is used in geometry are as follows:- Finding the area of a circle Finding the circumference of a circle Finding the volume of a sphere Finding the surface area of a sphere Finding the surface area and volume of a cylinder Finding the volume of a cone
What is the formula of r?
It depends on what r is and on what information you have. Even if r is a radius of a circular shape, you would have different formulae depending on whether: it is a sphere and you have the volume, it is a sphere and you have the surface area, it is a circle and you have the area, it is a circle and you have the circumference, it is a circle and you have the length and angle of an arc, it is a cone and you have volume and height, it is a cylinder and you have volume and height etc.
Where is pi used?
Pi can be used to solve many different things, such as the circumference, radius, diameter, or area of a circle, and the volume of a sphere.
What are everyday uses for pi?
Some of many examples are:- Finding the circumference of a circle Finding the area of a circle Finding the surface area of a sphere Finding the volume of a sphere Finding the surface area of a cylinder Finding the volume of a cylinder Finding the volume of a cone Finding the surface area of a cone

What is the formula for volume of a radius?
A radius is the distance from the centre of a circle (or sphere) to its circumference (or surface). It is a straight line and has dimensions [L]. It has only a length, no volume. So there is no such furmula.
What would the radius be if you have square root of 354?
That depends. What is that "square root of 354" ? Is it the circumference ? Diameter ? Area of the circle ? Area of the sphere ? Volume of the sphere ? The radius is different for each one.
HOW TO find the volume of a circle?
The area of a circle is 'pi' multiplied by the square of the circle's radius.The volume of a circle is zero.The volume of a sphere is (4/3 pi) multiplied by the cube of the sphere's radius.
What are 5 formulas that use pi in geometry?
Circumference of a circle given radius Area of a circle given radius Volume of a sphere given radius Surface area of a sphere given radius Converting degrees to radians or vice versa
