4 times pi. That is about 12.57.
Diametre = 2*radius so diameter = 24.8 metres.
Diametre is, since diametre = 2*radius
2*radius=diametre radius=2.1 Area=pi*(radius)^2 Area=3.1428*2.1*2.1 Area=13.86
pi * diameter
It is 25cm
2.35
92mm
Times the diametre by pi
40*pi metres
If you had a circle and cut along the diametre you would get two half cirlces.
4 times pi. That is about 12.57.
d = 11.46 inches
The circumference of a circle = pi*diametre = 2pi*radius
A diametre =2 aligned rayons it is a line from aside to a circle to another by passing from the center of the circle.
that is the radius. the diametre is the line going right accross the middle of the circle
tmes it by pi i think answer is 45.87 rounded up
