A circle that is 25.13272 cm in circumference.
The formula for circumference of a circle is 2πr. Since the radius is 4, the circumference is 8π or approximately 25.12 inches.
4 cm radius = Area of 50.26548 sq. cm.
The circumference of a circle with a radius of 4 ft is: 25.13 feet (r x 2 x Pi = circumference).
Circumference of a circle = 2*pi*radius = 8*pi or 25.13274123 units
A circle that is 25.13272 cm in circumference.
Circumference = 2*Ï€*r = 57.177 cm (to 4 dp)
Radius = 5/(2*pi) = 0.7958 cm rounded to 4 decimal places
The circumference of a circle with a radius of four is: 25.13
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
Well, darling, the area of a circle with a radius of 2 cm is approximately 12.57 square cm (π x radius squared). As for the circumference, it's around 12.57 cm (2 x π x radius). So, there you have it - a little geometry lesson to spice up your day!
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.
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
A circle with a radius of 4 miles has a circumference of 25.13 miles.
The formula for circumference of a circle is 2πr. Since the radius is 4, the circumference is 8π or approximately 25.12 inches.
2, because the radius is half of the circumference
8pi, the circumference is 2pi multiply by radius
