If it is just the radius, it is half of the diameter. If you are given the circumference, divide the given measure value by 3.14. Then, divide the result by 2 to get the radius! Have fun! If you need any help with other math formula's just post another answer. I'll write full, complete, and correct answers that I'm sure about.

If 8 is the radius what is the circumference?
The formula for calculating the circumference of a circle is 2pr where r=radius and p (pie) = 3.1416 so for your question thr circumference = 2 x 3.1416 x 8 = 50.2656
How do you calculate the radius of s semicircle?
Calculating the radius of a semicircle depends on what information about the semicircle is given.
What is the formula for calculating surface area of hemispherical dished end?
The area of a sphere is 4 (pi) (radius)2. The area of 1/2 of the sphere is 2 (pi) (radius)2. If you want to add in the flat end of the hemisphere, that makes the total surface area 3 (pi) (radius)2.
What is the formula for calculating perimeter of dodecagon?
Assuming the shape is a regular dodecagon, the formula for calculating the perimeter for a dodecagon of side length n is equal to 12n.
What is the point of calculating Pi?
What do you mean 'finding'? Pi is the ratip of the circumference to the radius of a circle.
