Question

if the radius of circle is d.
What will be its diameter ?​

Answer 1

Answer:

2d

Step-by-step explanation:

given that radius of a circle is denoted as d,

then the diameter is given by 2*d = 2d

Answer 2

Answer:

Take the circumference of a circle and divide it by Pi. For example, if the circumference is 12.56, you would divide 12.56 by 3.14159 to get 4, which is the diameter of the circle. ... Use “D = R x 2”, in which "D" equals diameter and "R" equals radius, to solve for the diameter using the numbers you got earlier.
