A circumference of 21.99 cm

The radius is 7cm

Assuming that what you mean is that the diameter is 7cm...Pi x 7 = 21.99114858C = 22

Circumference of the circle: 2*pi*7 = 44 cm rounded up to the nearest whole number

pi = 21.99/7 pi = circumference/diameter Just multiply your diameter by pi to get a circumference.

C=2 pi R

21.99113 approximately... * * * * * Accurate to 5 decimal places but WRONG by a factor of 2. Circumference = 2*pi*radius so radius = 7 cm => circumference = 43.98 cm.

The area of a circle is pi*r2 and its circumference is 2*pi*r where r is the radius = half the diameter. So r = 3.5 cm. Then area = 38.48 square cm and circumference = 21.99 cm As to the circumstance of the circle, that is rather a personal question!

the reason is because a circle is divided in 3 parts and the left overs are .14 so when you measure the ciecumference, you times the diameter by 3.14 and you get the correct answer to the question.EX: R=3.5cm D=7cm 7cm so that is why we use pi . x 3.14 -------- 21.98
