multiply the radius times 2

The diameter is Always twice the radius. So, 20*2 would equal 40.

The diameter is 2 times the radius. So just double the radius. Let's say:
radius = 20
(20) x (2) = 40
so...the diameter is 40.

The circumference of a circle is an identical as: 2 x pi (3.14) x r if you're given the diameter, divide it through 2 and also you've the radius. solutions: a million) 40 8/2 = 24mm radius 2 x 3.14 x 24 mm = 100 and fifty.seventy 2 mm 2) you paintings it out

the diameter would equal 2radius because radius is half the circle and diameter is the complete length of the circle so ur example would be 2(20)=d=40

Diameter is the width of the circle, so multiply the radius by 2 and you get 40.

a Radius is half a Diameter. So, if your radius is 20 ft, your diameter is 2x20, or 40.

d = 2r
Ex--
d = 2 (20)
d = 40 ft
