raidus means a scientific answer and is to be measured for something for example the earth it is 6400km raidus
A = 50.265 square units.
the raidus of a circle is the distance from the middle of a circle to any point.
6378.1 kilometres. Which is 3969 miles.
300 feet
The sun's radius is approximately 696340 Km.
circumference is diameter times 3.14 diameter is raidus times 2 1 times 2 equals 2 3.14 times 2 equals 6.28 circimference is6.28
if you have a radius in a circle do you use A=(3.14)d2
64 pi ie just over 201 sq cm
Divide the circumference of the earth by (2x3.14) and that's roughly the answer.
You don't even need the height.The radius is just Circumference/2 pi
circumference is pi times diameter (8.6 +8.6) x 3.1415926=___mm round off answer as needed
There is no such thing as a mean square of a single number.
