Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
Circumference of circle: 2*pi*4.9 = 30.788 rounded to 3 decimal places
The radius of a circumference is half of the diameter. To find the radius of a circumference with a length of 64cm, you need to divide the circumference by 2π (since the formula for the circumference of a circle is C = 2πr). So, the radius would be 64cm / (2π) ≈ 10.19 cm.
circumference = 2*pi*15.8 = 99.27432785 or 99.274 cm to 3 d.p.
Circumference: 2*pi*3 = 6*pi inches Area: pi*3 squared = 9*pi square inches
The circumference of a circle if its radius is 3 is about 18.85
A circle with a radius of 3 units has a circumference of 18.85 units.
A circle with a radius of 3 units has a circumference of 18.85 units.
The circumference of a circle with a radius of 3 m is: 18.85 m.
radius of the circle = 11.32/(2*pi) = 1.802 yards rounded to 3 decimal places
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
A circle with a radius of 3 inches has a circumference of 18.8 inches
The radius is 3.
The circumference of a circle when the radius is 3 inches is: 18.8 inches (r x 2 x Pi = circumference)
Circumference of a circle = 2*pi*radius or diameter*pi
the question makes no sense? 3 yards doesnt have a circumfernce. Only Circles have circumfernes ( the perimeter of a circle ) BUT..in case you want a cirlce of radius 3 yards, then it's circumference is 6Pi, and if instead you diameter is 3, than it is 3Pi.
