1.48
atomic radius of I is 1.33
given 2.81
2.81-1.33=1.48
raidus means a scientific answer and is to be measured for something for example the earth it is 6400km raidus
the raidus of a circle is the distance from the middle of a circle to any point.
300 feet
6378.1 kilometres. Which is 3969 miles.
A = 50.265 square units.
The sun's radius is approximately 696340 Km.
if you have a radius in a circle do you use A=(3.14)d2
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
Divide the circumference of the earth by (2x3.14) and that's roughly the answer.
The image of the star will be 67.5 cm from the mirror because focal length is the raidus of curvature multiplied by 2 or (2)(C). So, therefore, 150 / 2 will give the focal length which would also be 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
