Circunference is equal to 2pi * radius, there for 14 divide by two equal 7 because radius is half of diameter then you will need to put in your calc... 2(3.1416)*7 and the answer will be the circunference. Or you can simply say 14 pi
I think the magic word here is "approximate", from which I believe the question hopes you will use the well known approximation for pi (=22/7).
So pi times diameter is 22/7 x 14 = 44km
Well, honey, if the circumference of a circle is 14 cm, then we can use the formula C = πd to find the diameter. Plug in the given circumference and solve for the diameter. So, the diameter of the circle would be approximately 4.45 cm. Hope that clears things up for you, sugar!
You need to use the formula for solving the diameter of a circle which is C = pi x D = 3.1416 x 14 = 43.98 inches (approx)
You need to understand the concept of the number pi. pi is the the number of diameters you can "wrap" around a circle. The number is 3.14... So if you had a circle with a diameter of 1 cm then the circumference would be 3.14 x 1 which equals 3.14 cm Since the diameter is 14 cm the circumference is 3.14 x 14 cm The equation that deals with this is ... circumference = pi x diameter or c=pi x D
43.96
Circumference is about: 44 Area is about: 153.94
It is: 14*pi = 44 units of measurement rounded
If a circle has a diameter of 14, the circumference is: 43.98.
The circumference of a circle with a diameter of 14 is: 43.982
The circumference of a circle 14' in diameter is about 43.98'
The circumference of a circle with the diameter of 14 ft is: 44 feet.
Multiply by pi , so 14 x 22/7 = 44cm approximately.
A circumference of 43.98 units.
The circumference is approximately 43.98
diameter = circumference/pi
Well, honey, if the circumference of a circle is 14 cm, then we can use the formula C = πd to find the diameter. Plug in the given circumference and solve for the diameter. So, the diameter of the circle would be approximately 4.45 cm. Hope that clears things up for you, sugar!
Diameter = 14/pi cm
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?
