How do you find the circumference of a circle if you know the radius?
Multiply the radius by 2 to get the diameter. Then multiply the diameter by pi to get the circumference. Example: If radius = 2 inches, diameter = 4 inches circumference = 4 x pi = 4 (3.1416) or about 12.57 inches
What is the circumference of a circle with the radius if 4?
The circumference of a circle can be found with this formula: Circumference = 2*(radius)*∏ where ∏ can be rounded to 3.14 Plugging in your radius of 4: Circumference = 2*4*∏ = 8*∏ which is around 25.13.
What is the formula for finding the circumference with radius?
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
If the radius of a circle is 4 then what is the circumference?
8pi, the circumference is 2pi multiply by radius
To the nearest hundredth what is the circumference of a circle with a radius of 4?
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
How do you find the circumference of a circle with a radius of 4?
Circumference of a circle = 2*pi*radius = 8*pi or 25.13274123 units
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 the circumference and area of a circle that has a radius of 4?
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.

What is the circumference of a circle with the radius of 4?
The circumference of a circle with a radius of four is: 25.13
What is the radius of a circle with the circumference of 4?
2, because the radius is half of the circumference
If the radius of a circle is 4 then what is the circumference?
8pi, the circumference is 2pi multiply by radius
Find the ratio of the circumference of 4Cm?
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
What is the circumference of a circle if the radius is 4 inches?
The circumference of a circle if the radius is 4 is about 25.13 units. (C = r x 2 x Pi)
What is the radius if circumference is 25.12?
circumference = 2 × π × radius → radius = circumference ÷ (2 × π) = 25.12/(2π) ≈ 4 units
