Area of a circle is Pi x r x r (Pi r squared.) 3.142 x 10 x 10 square feet = 314.2 square feet.
The surface area is 1,256.6 inches2
62.832
The circumference of a circle with a radius of 20ft is: 125.7 feet (radius x 2 x pi = circumference).
OK, The circumference of a circle is 2 times pi (3.14) times the radius. SO the radius is = to circumference (5cm) divided by 2 times pi. 5 divided by 6.28 = .796 time 2 gives us a diameter of = 1.59 centimeters. We could also use Pi = cicumference/diameter therefore 3.14=5/x Multiply both side by x and 3.14 x = 5 Divide both sides by 3.14 and you get x= 5 divided by 3.14 which equals 1.59 cm
113.1 meters.
r = 159.15 m
The circumference of a circle when the diameter is 30 is: 94.25
The circumference of a circle with a radius of 10 inches is about 62.83 inches.
A circle with a radius of 10 m has a circumference of 62.83 m.
The radius of this circle is 10 units.
A circle with a radius of 10 cm has a circumference of 62.83 cm.
circumference of a circle = 2*pi*radius or pi*diameter
A circle with a radius of 10 inches has a circumference of 62.8 inches.
If the circumference of a circle is 10 feet the radius is: about 1.592 feet. For this type of calculation, divide the circumference by Pi (about 3.1416). This gives you the diameter. Next, divide the diameter by two to get the radius.
The circumference is 62.8318531 inches.
The radius is about 1.6 units.
The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)
formula for circumference is 2(pi)(radius) therefore: 10=2(pi)(radius) solving: radius = 10 / (2 pi) radius = 1.59
