The diameter of a circle that has a circumference of 113 mm is about 35.97 mm
A circle with a radius of 50 mm has an area of 7853.98 square mm
The circumference of the circle with a diameter of 64 mm is 64*pi = about 201 mm
188.40 mm
9 mm
Circumference = 2*pi*4 mm or 8*pi mm
27.2 mm
I'm wondering what the original, or book, question actually asks, but in this case, a it is a circle larger in radius, diameter and circumference by the ratio 4:3; and in area by the ratio 16:9.
Diameter of circle: 13/pi = 4 mm rounded to the nearest integer
A circle with a diameter of 4 mm has an area of : 12.57 mm2
The circumference of a 40 mm circle is: 126 mm
The circumference of a circle with a diameter of 110 mm is 345.58 mm
The diameter of a circle that has a circumference of 113 mm is about 35.97 mm
A circle with a radius of 6 mm has a circumference of 37.7 mm
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
The circumference of a circle that is 16 mm in diameter is 50.27 mm
By unit of length and distance and conversion ,we can say that 1 mm=0.1 cm 4 mm=0.4cm
