It is the name given to the straight line from the centre of a circle to its circumference when that distance is 28 cm.
It is 14 cm.
28 pi cm, about 88 cm
Curved surface area: pi*21*28 = 1847.256 square cm rounded to three decimal places
The radius of a 2 cm circle is: 1 cm
Using 3.14 as Pi the area of circle is: 2461.76
14 cm
It is 14 cm.
Diameter = 2*radius = 28 cm
28 pi cm, about 88 cm
The radius is 28 cm so the circumfecrence is 2*Ï€*28 cm = 56Ï€ cm which is the distance travelled by 1 revolution. So the distance travelled in 300 revolutions = 300*56Ï€ cm = 16800Ï€ cm = 52778.76 cm = 527.8 metres approx
The diameter would be 28 cm.
Using 3.14 as Pi the area of circle is: 2461.76
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
Curved surface area: pi*21*28 = 1847.256 square cm rounded to three decimal places
Area = 22/7*282 = 2464 square cm
The radius of a 2 cm circle is: 1 cm
The radius is 5 cm.
