If you have the diamater 4.2cm how would you find out the circumference?

Circumference of a circle = 2*pi*radius or pi*diameter
Circumference = pi*4.2 = 13.19468915 or 13.2 cm to one decimal place

What formula is used to find the diameter when you know the circumference?
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
How do you find the diamater and of a cylinder with only the circumference and height?
Divide the circumference by the value Pi - this will give you the diameter.
How do you find the diamater of a circle by knowing its curconferance?
By dividing the circumference by 2*pi will give you the radius and twice the radius gives you the diameter.
How do you solve the circumference of a circle?
to find the circumference of a circle, which is the distance in the outside of the circle you need to use the following formula: C=dx 3.14 or circumference equals diameter times pi. The diamater is the length of the circle from end to end. Not very difficult.
What is another way to find the area of a circle given the circumference?
Divide by pi to get the diameter. Divide the diamater by 2 to get the radius. Pi times radius squared.
Find the area of the triangle whose perimeter is 42cm long side is 16cmdiffrence between other two is LCM?
so 42cm = 16 is 26cm if the difference between the other 2 was the LCM, it would equal more than 42. This is impossible to calculate
How do you find the circumfreence?
To find the circimfrence you need to do PI x Diameter Example: If the radius is 6 Yds and they are asking you do find the circumference you would do the formula. soooo...... 3.14 x diameter. We don't have the diamater but If we know the radius then we could find that out by doubling that number. soooo.... 6+6=12 soooo..now you would do...... 3.14 x 12= 37.68 ***and always remember. You need to know this. PI=3.14 orrr.................22/7
How to find the diamater of a circle?
You double the radius.. if the radius is 10 the diameter is 20.
Find the circumference of a circle with a diameter of 726.4 centimeters?
(circumference=2πr or πd) so the circumference in exact form would be π726.4
What is the circumference of the circle if the radius is 80m?
the way you find the circumference is 2xpixr or pixdiameter. so it would be 2x80xpi
How do you find somethings circumference?
it would be pi * radius squared
In a circle the circumference and diameter vary directly Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second ci?
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
