What is the diameter of a circle if its radius is 30cm?
60cm
What is the diameter of a circle if the circumference is 30cm?
30/pi cm
What is the diameter of 30cm?
The diameter of a circle is the distance across it, passing through the center. If the diameter is 30 cm, that means the full width of the circle from one edge to the opposite edge is 30 cm. Therefore, the diameter is simply 30 cm.
What is the area of a circle where the diameter measures 30 cm?
Diameter = 30cm so radius = 15 cm. Then Area = pi*r2 = 706.9 cm2
What are two ways a circle and a cylinder the same?
The bases of a cylinder are circles and both have circumferences Area of the base of cylinder and a circle is pi*radius2 Circumference of a cylinder and a circle is 2*pi*radius or diameter*pi

What is the circumference of a circle with a diameter of 30cm?
circumference = diameter X pi pi = 3.1416 circumference = 30cm X 3.1416 = 94 cm
If a circle has the diameter of 14 inches then what is its circumferences?
14 pi inches = a whisker under 44 inches
What are circumferences?
The perimeter of a circle

What are two ways a circle and a cylinder the same?
The bases of a cylinder are circles and both have circumferences Area of the base of cylinder and a circle is pi*radius2 Circumference of a cylinder and a circle is 2*pi*radius or diameter*pi
Calculate the circumference of a circle with each diameter?
Multiply each of the diameters by pi (pi = 3.14159265 or 3.14 for rough approximation) to find the circumferences of the circles.
What are the circumferences of the planets?
It is the planet's diameter multiplied by pi
What is the formula to finding circumferences?
If it's a circle, then it's pi*diameter or 2*pi*radius.If it is an ellipse, the circumference (perimeter) is an infinite series with an approximation based on its eccentricity (which for a circle is zero).(see the related link)
