What is the formula to find a circumference if the radius is 4 and the diameter is 8?
pie multiplied by the radius.
What is radius if diameter is 8?
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
If the radius is 4 what is the diameter?
radius *2 = diameter so then plug the radius in... 4*2=8 8 is the diameter of the figure.
How is 25.133 the circumference of a circle with a radius of 4?
Radius = 4 so diameter is 8. 2xR = D Circumference formula: C = pi x diameter So 25.133 = 3.14 x 8
What is circumference of a circle with a radius of 4 cm?
circumference formula is pi(diameter) diameter is 2(radius) radis=4; diameter=2(4)=8 pi(8)=circumference of the circle...this is the EXACT answer plug it into a calculator and you will get 25.1327412287 your welcome ;)
If the radius is 4 then what is the diameter?
Diameter = 2 times radius = 8
If the radius of a circle is 4 cm then what is the diameter?
The diameter would be 8cm, because the diameter is always double the radius. That's why the formula 2'Pi'r is also known as 'Pi'd.
A flowerpot has a diameter of 8 what is the radius?
Radius = 1/2*Diameter Thus, 1/2*8 = 4 Flowerpot has a radius of 4.
What would be radius of a circle with a diameter of 8 inches?
Radius = 1/2 diameter. So, if the diameter is 8", then radius of the circle is 4".
What is the radius of a circle with a diameter of 8 centimeters?
Radius = Diameter / 2 In this case, diameter = 8 cm so radius = 4 cm
How do you find the diameter without the circumference?
The diameter of a circle can be found without the circumference using the formula d = 2r. This formula requires that you know the radius of the circle which is half of the diameter. To calculate the diameter you need to multiply the radius by 2. For example if the radius of the circle is 4 then the diameter would be 8 (4 x 2 = 8).You can also find the diameter of a circle if you know the circumference. To do this use the formula c = d. By rearranging the equation you can calculate the diameter as d = c/. For example if the circumference of the circle is 12.5 the diameter would be 4 (12.5/ = 4).
What is the radius of a circle that has a diameter of 8 cm with formula?
let d = diameter let r = radius r = d ÷ 2 r = 8 cm ÷ 2 = 4 cm
