Area = (pi) x (Radius)2
(Radius)2 = Area/pi
Radius = sqrt(Area/pi)
Diameter = 2 x radius = 2 x sqrt(Area/pi)
Measure the diametre of the circle and divide by two to give the radius.
An ordinary dinner plate has a diametre of 32cm, which gives it a radius of 16cm a= pi * r2 a = 804 cm
Surface area = (2*pi*32) + (pi*6*9)) = 72*pi which is about 226 square cm
It is 25cm
2.35
2*radius=diametre radius=2.1 Area=pi*(radius)^2 Area=3.1428*2.1*2.1 Area=13.86
diametre of circle
The question has no answer, because squares don't have diameters.
The diametre of Pluto is 2,320km
tmes it by pi i think answer is 45.87 rounded up
The circumference of a circle = pi*diametre = 2pi*radius
The average diametre of the planet Mars is approximately 6,786km.
Diametre is, since diametre = 2*radius
Measure the diametre of the circle and divide by two to give the radius.
