If its diameter is 10 inches then its circumference is: diameter*pi If its radius is 10 inches then its circumference is: 2*pi*10
Circumference is 2 times pi times radius, so the circumference of this circle is 2 times pi times 5, or 10 times pi. If a decimal answer is needed, pi is approximately 3.14, so C=31.4
circumference of the circle = 2*pi*10 = 20pi units of measurement length of arc = (120/360)*20pi = 20.944 units (rounded to 3 decimal places)
The formula for the area (A) of a circle is A = πr2. If the area is 100π then 100π = πr2 : 100 = r2 : r = √100 = 10. The radius is of length 10 units.
10=2*pi*r Solve for r: 10/(2*pi)=r 1.591=r so radius rounded to nearest tenth is 1.6
The radius of this circle is 10 units.
The circumference of a circle with a radius of 10 inches is about 62.83 inches.
radius = 20pi/2pi = 10 units area = pi*102 = 100pi square units
Divide the circumference of 62.8 by 2*pi to find the radius which is about 10 units Area of the circle: pi*10*10 = 100*pi square units
A circle with a radius of 10 m has a circumference of 62.83 m.
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
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.
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 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)
