No. Diameter = 2 x r
Yes it is, where r is the radius
Area of a Circle: A = (pi) * r ^ 2 (Area equals Pi Times the radius Squared) R = 3/2 (Diameter = 3, Radius = 1/2 of the Diameter) A = 3.1415 * (3/2)^2 A = 3.1415 * 2.25 A = ~7.068 Square Feet
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
12
the diameter is 2times the radiusr=33ind=66in
radius=1/2 diameter so R=3cm
The radius of a circle with diameter or 8 inches is 4 inches. The diameter equals 2 times the radius or d=2*r. --> 8 in = 2*r so, r = 4 in
if r=5z and 15z =3 then r=10y
72, double the radius because radius is half of the whole diameter.
I
r = 5z 15z = 3y (divide by 3 to both sides) 5z = y r = y
