What is surface area of spherical shell?
Surface area of a sphere = 4*pi*radius2 For a spherical shell, surface area = surface area of outer sphere - surface area of inner sphere = 4*pi*(outer radius)2 - 4*pi*(inner radius)2 = 4*pi*[ (outer radius)2 - (inner radius)2 ]
How do you measure the radius?
measure from the middle out to one side
What is the measure of the radius of M?
7.4
How do you find the area of a balloon?
You mean the surface area, right? Assuming the balloon is approximately spherical, you can measure the diameter, divide by two to get the radius & plug that into this formula.A=¾πr²Where A is the area, r is the radius and π is the ratio of the circumpherence to the radius of a circle. 3.14 or 22/7 are good approximations to π, also a decent calculator will have a better approximation built in. To look it up search for "pi" (that's the Greek letter's name).
What is the measure of the radius of N if on12.7?
12.7 units
What is the radius of England?
Radius is a sensible measure to use with a circular (or spherical) shape. England is neither.
What is the radius of a 32 foot spherical water tank?
volume of spherical = 4/3*Pi*Radius^3 = 4/3*3.14*32^3=137188
What is the percent uncertainty of a spherical beach ball with radius 0.84 - 0.05m?
The uncertainty in radius is approx 5.95%.
What units are used to measure the radius of a atom?
pico meter
What is the radius at the equator of mercury?
It's about 2440 kilometers. Mercury is almost spherical, so the radius is about the same everywhere.
What is the spherical radius of 1 foot?
It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.
Is plain mirror also an spherical mirror of infinite radius?
Yes
How many spheres of mercury each with a radius of r should combine to form a single sphere with a radius of 3r?
Volume of the sphere varies as the cube of the radius.Tripling the radius increases the volume by a factor of (3)3 = 27.It takes 27 spherical volumes with radius 'r' to fill one spherical volume with radius '3r'.
What is the measure of the radius 15.4?
15.4 units - whatever units were used.
What is the instrument used to measure the radius of an egg?
the instrument used to measure the radius of an egg is episometer
How can a spherical mirror become a plane mirror?
By increasing its radius of curvature to infinity.
Which doesnot change when spherical mirror is broken?
Its radius of curvature and its reflecting property
