Diameter = Radius*2 = 30 cm.
C = ~47.12 cm
double the radius to get the diameter = 30 multiply by pi (3.1415...) = 92.245 cm
The formula for the circumference of a circle is C = 2πr where r is the radius. This formula can also be expressed as C = πd where d is the diameter as the diameter is twice the radius. C = 15π = 47.12cm (2dp)
15cm = 5.9 inches.
The circumference of a circle with diameter of 15cm is about 47.12cm
The circumference of a circle, if the diameter is 15cm, is about 47.12cm
The circumference of a circle with diameter of 15cm is about 47.12cm
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
Diameter = Radius*2 = 30 cm.

7.5cm (r = d/2)
Ah, what a lovely question! To find the circumference of a cylinder, you'll want to use the formula 2πr, where r is the radius of the cylinder. Since the diameter is 16 inches, the radius would be half of that, which is 8 inches. So, the circumference would be 2 x π x 8, which is approximately 50.24 inches. Keep painting with those happy little numbers!
Using 3.14 as Pi the area of circle is: 379.94
