How do you figure out diameter and circumference?
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
What is the radius of a circle circumference is 38?
If the circumference is 38, the diameter is 38/pi. Since the radius is half of the diameter, the radius is 19/pi.
What is the diameter of a circle if it's circumference is 4 and a half inches?
Divide the circumference by the number pi, which is approximately 3.14.
What is a circumference of a circle whose diameter is 250 cm?
The radius is half the diameter, which is 125cm. 2pir is 2x125x3.14159 which is 785.4cm
How do you find the distance around a semicircle?
It is half the circle's circumference plus its diameter.
Is the circumference half of the diameter?
Nope. Half the diameter is the radius. Circumference is the distance around the edge.
How do you figure out diameter and circumference?
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Is the radius half the circumference?
No it is half the diameter.
What is the circumference of a 6 diameter circle halfway?
A circle with a diameter of 6 has a circumference of 18.85. Half of that is 9.425
How to find the radius of a circle with the circumference?
Divide circumference by pi, that gives diameter. Radius is half of diameter
How do you find the radius of a circle is you have the circumference?
pi X diameter finds the circumference so circumference divided by pi will leave the diameter. half the diameter to find the radius
How do you calculate the radius from the circumference?
Of a circle: divide the length of the circumference by the value of Pi (about 3.14159). The answer is the diameter. Half of the diameter is the radius
If you Give a circle with a diameter of 4 what is the circumference?
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
What is the circumference of a circle with a diameter of 7?
the circumference is 3 1\2 (3 and a half)
What is the difference between circumference and radiuas?
The circumference is the distance around. The diameter is the distance across. The radius is half the diameter, from the center to the rim.
Do the radius equal half of the circumference?
No because it equals half the diameter of a circle
How do we find a perimeter of a semicircle?
It is its diameter plus half of its circumference
