If 12.5 refers to the diameter, then the circumference is 39.3 units, approx.
Assuming that "it" refers to diameter, the radius is 7 cm and the circumference is 44.0 cm.
The answer depends on what the "16 inch" refers to.
The answer depends on whether 5m refers to the radius or diameter.
Both are the measurement of the outside edge of a figure, circumference relates specifically to a circle, and perimeter refers to polygons.
If 12.5 refers to the diameter, then the circumference is 39.3 units, approx.
It depends on what the "32in" refers to: circumference, diameter, radius.
Assuming that "it" refers to diameter, the radius is 7 cm and the circumference is 44.0 cm.
Assuming 9m refers to the radius, the diameter is 18 m and the circumference is 56.5 m
Since 'circumference' refers to a circle, if the lake is a circle with an area of six acres, the circumference would be: 2,563 feet.
The answer depends on what the 59.66 refers to: radius, diameter?
The answer depends on what the "16 inch" refers to.
The answer depends on whether 5m refers to the radius or diameter.
The answer depends on what the "16 inch" refers to.
Both are the measurement of the outside edge of a figure, circumference relates specifically to a circle, and perimeter refers to polygons.
The circumference of a circle is 2 pi r, where r is the radius, or it is pi d, where d is the diameter.there is no circuference of pi. Circumference refers to the outer edges of circles
If the question refers to a square, then circumference = 4d, where d is the length of a side. 20 = 4d therefore d = 20/4 = 5 ft. If the question refers to a circle with a circumference (C) of 20', then C = 2πr, where r is the radius of the circle. 20 = 2πr therefore r = 20 ÷ 2π = 3.18 ft If the question refers to the circumference of a circle with radius 20', then C = 2π x 20 = 40π = 125.66 ft
