What is the best estimate of the area of a circle with a diameter of 10 cm?
You have to calculate the radius - half the diameter. Then square the radius, and multiply by pi (approximately 3.1416). If you want to do a mental estimate, round pi to 3.
Calculating radius and diameter?
Radius = Diameter/2 Diameter = 2* Radius
What is the Diameter to a radius of a circle?
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
What is the circumference of circle if the radius is 48?
The circumference C of any circle is equal to pi*diameter. The diameter is equal to the radius times 2. So, for a circle with radius 48, it has a diameter of 96, and a circumference of 96*3.14=301.44. This of course is using 3.14 as an estimate for pi.
Diameter of circle..its radius?
A radius is half of a diameter. Example Diameter:4 Radius:2

How can you estimate the length around a circle when youknow the length of the radius or diameter?
2*radius*pi or diameter*pi, pi = 3.14 (rounded to the nearest tenth)
Calculating radius and diameter?
Radius = Diameter/2 Diameter = 2* Radius
How do you get the diameter from the radius?
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
What is the Diameter to a radius of a circle?
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
The length of a radius is the length of a diameter?
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
What is the circumference of circle if the radius is 48?
The circumference C of any circle is equal to pi*diameter. The diameter is equal to the radius times 2. So, for a circle with radius 48, it has a diameter of 96, and a circumference of 96*3.14=301.44. This of course is using 3.14 as an estimate for pi.
How do you get the radius when you have the diameter?
radius = diameter/2
What is radius if diameter is 8?
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
Diameter of circle..its radius?
A radius is half of a diameter. Example Diameter:4 Radius:2
What is the relation between radius and diameter?
The diameter of a circle is twice its radius.
How do you calulate radius into diametre?
the radius is one-half the diameter radius = diameter/2 diameter = 2 x radius
