94.985 or approximately 95 square centimeter.
pi*112 = 380 square cm
If you mean the area of a circle then it is: pi times radius squared
11cm x 5cm = 55cm2.
Because when you do not add units to a number,your answer will be ordinary like for example,if your answer is 11cm,and,you did not put the units,which is cm.,then your answer will not be thought as a centimeter.Your answer will be thought as something else like if your answer is 11cm. and you did not put cm.,it will be thought like 11meters or 11cats.
The circumference of a circle, if the radius is 11cm, is about 69.12cm
11cm * pi 34.5575192 centimeters
22
C = 69.115 cm
A circumference of 34.6 cm
94.985 or approximately 95 square centimeter.
pi*112 = 380 square cm
It is 1/2*pi*r2 = 190.1 cm2
If you mean the area of a circle then it is: pi times radius squared
Oh, what a happy little question! If the radius of a circle is 5.5cm, we can find the diameter by multiplying the radius by 2. So, the diameter of this circle would be 11cm. Just a simple little calculation to bring a smile to your face!
11cm=110mm
