What is the circumference of a circle that is 9cm wide?
The circumference of a circle that is 9 cm wide is: 28.274 cm
What is the radius of a circle with a diameter of 9 cm?
To calculate the radius is very easy, the formula is d/2 where d is diametre. therefore according to d/2 = 9cm/2 which is equals to 4.5 cm Result : the radius of a circle with a diameter of 9 cm is 4.5 cm.
What is inside circumference and outside circumference?
u cant have circumference inside a circle inside of a circle is called area out side the circle its called circumference. If you are calculating the circumference the formula is C(circumference)=pi(3.142)*d(diameter) so its C=pi*d note: if u want the accurate result press pi on a calculator which is like a table but the surface of the table is sticking out. now for the area A(area)=pi(3.142)*r squared(radius) so its A=pi*r squared. so heres an example work out the circumference if the diameter is 5cm so you do 5cm which is the diameter and multiply it my pi. So the answer is for two decimal place is 15.71cm here's another example using the radius the radius is half the diameter so in this case the radius is 2cm multiply it my two which gives 4 and then multiply my pi. Now example for area the radius is 3 but then i have to square it so i do 3(squared) which is 9cm(squared) then * pi which will give you 28.27cm(squared) area is inside a shape. hope this helped if you need help e-mail me at: nik.kita@hotmail.co.uk
What is the area of a circle that has a diameter of 9 cm?
The area of a circle is figured out using the formula Now, the circle we are given has a radius of 9cm. So, the area of the circle would be: Area = 3.14 x (9)2 = 3.14 x 81 = 254.34 cm2 The area of the circle in question is 254.34 cm2
How do you find the perimeter of 9cm 5cm 9cm 5cm?
9cm + 5cm + 9cm + 5cm = 28cm
The radius of a circle is 9cm what is the circumference of the circle?
56.549 cm
How is the circumference of a circle with radius 9 cm related to the circumference of a circle with diameter of 9cm?

What is the circumference of a circle with a radius of 9cm?
56.549 cm
What is the circumference of a circle with a radius of 9cm show circulation?
Circumference of the circle: 2*pi*9 = 18*pi cm
What is the cicumfrence of a 9cm circle?
The equation for circumference is C = 2*pi*r, where r is the radius of the circle and pi is a constant = 3.14159... Assuming that you mean a 9cm radius, the circumference is therefore: C = 2*pi*r = 2*pi*9cm = 18cm*pi = ~56.549cm
What is the circumference of a circle that is 9cm wide?
The circumference of a circle that is 9 cm wide is: 28.274 cm
How do you divide a circle with 9cm diameter in three equal parts?
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
