The answer will depend on what r is meant to be. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.

U value of r-19 insulation?
The U value is the inverse of the R value. For R value 19 insulation the U value is 1/19, or 0.0526.
Surface area of sphere with volume 0.2 meters?
For the question to have any meaning, the volume should be in cubic metres, not metres. The surface area of a sphere of radius r is 4*pi*r*r and its volume is 4/3*pi*r*r*r. Use the second equation to find the value of the radius, r and then use that value in the first equation to calculate the surface area.
If the diameter is 17 what is the area?
The formula for the area of a circle is r*r*pi, where r is radius. Radius is half of the diameter, so to find the area you first need to find half of 17. 17/2=8.5 Then put that in the formula to find the answer. 8.5*8.5*3.14=226.865 with a more accurate value for Pi you get 226.98

Find the smallest number in a GP whose sum is 38 and product 1728?
Let the three numbers in GP: a/r, a, ar---------(A)Where '^' is power of . . .Sum of these numbers are:a/r +a +ar = 38a(1\r+1+r) = 38 ---- (1)Product of these numbers are:a^3 = 1728= (12)^3a = 12Putting the value of a in (1) you will get:12(1\r+1+r) = 38And factorising, we getr = 2/3 or r = 3/2Sub. the r and a value in (A), we get8,12,18 or 18,12,8. When a = 12And smallest no. is 8.
Explain why there is only one geostationary orbit?
There is only one geostationary orbit because in order for any mass m to orbit the Earth (ME) the gravitational force: EQ1: Fg = GmME/r^2 has to be such that it is equal to the required centripetal force for uniform circular motion: EQ2: Fc = mv^2/r where v is the velocity of m at radius r (distance from the center of the Earth) and: EQ3: v = 2(pi)(r)(f) f is the frequency of rotation in revolutions per second. For geostationary orbit the satellite must be in a fixed position (it must have the same frequency of rotation or angular velocity as the Earth's rotation) relative to the Earth and orbit above the Earth's equator. The necessary velocity to satisfy Fg = Fc is a specific value, therefore (since pi and f are fixed values) r is the only variable in EQ3. There is a specific orbital radius for geostationary orbit of any mass m.
What is the answer to the neopets Lenny conundrum round 271?
Distance= (r - R)/1000 Reference= http://lennyconundrumsolutions.blogspot.com/2008/07/round-271.html r= the distance between the Neopia's center of mass to the Kreludor moon's geostationary orbit (unsure of actual value) R= d/2 = 800 km = 800,000 m (radius) We use 1000 factor in the above equation because we want to get in kilometers. Round that distance number and we get the answer.
How does the gravity at the altitude the space shuttle flies compare with the gravity on earth?
if you know earth surface radius and acceleration due to gravity, you can use the following equation to find acceleration at another radius (say geostationary orbit where the communication satellite's are).a = k / ((d/r)^2).where:a = required acceleration at goestationary orbit ( ? (m/s)/s)k = earth surface acceleration due to gravity (9.81 (m/s)/s)d = geo stationary orbital radius (42 170 000 metres)r = earth surface radius ( 6 371 000 metres).so acceleration at geostationary orbit = 0.224 (m/s)/scompared to acceleration on earth = 9.81 (m/s)/s.say shuttle = 25 000 kg(weight on earth) f= m*a = 25 000 * 9.81 = 245 250 newtons(weight at orbit ) f=m*a = 25 000 * 0.224 = 5 600 newtonsnote: the force on the shuttle in orbit is balanced by the centripetal force created by its motion in a circle, its required velocity can be calculated from:v = sq.root(a * d)v= 3073 m/s
How do find the circumference with a value of 3.14?
C=2(pi)r, so C=(2)(3.14)r
Area of a circle is 36 square centimeters what is the circumference of the circle?
The area of a circle with radius r is pi*r*r and its circumference is 2*pi*r Use the first to find r and then use that value of r in the second to find the circumference.

What is the differenceperiod and orbit radius near earth and geostationary satellites?
(Assuming sattelite mass is small enough compared to that of earth so it can beignored in the calculations)Basically, the nearer you are, the faster you have to go.CALCULATING ORBITAL VELOCITY (v) (radius given)G = newtons gravitational constant (6.673 * 10-11)M = mass of earth ( 5.974 * 1024 kg)r = orbital radiusv = orbital velocityFor any given orbital radius, only one velocity will sustain stable orbit.(Acceleration due to gravity) = (Acceleration due to centripetal force)(G*M / r2) = (v2 / r)For stable orbit velocity, first choose orbital radius.Rearrange (G*M / r2) = (v2 / r) to isolate v (stable orbit velocity)v = square root ( (G* M) / rExample:The minimum altitude where you will be free of atmosphere gases, and thus air resistance is about 100 km (100 000 metres), from earths centre thats= 6 471 000 metresThe velocity required to produce stable orbit = square root ((G*M) / r)= 7849 metres per second (17 558 mph)Orbital time = ((2*pi*r) / v) secondsGEOSYNCHRONOUS ORBITA 360 degree rotation of the earth ( sidereal day ) takes 23.934 hours( 86164 seconds), for geostationary orbit only one orbital radius is suitable that will result in equalling this time.by trial and eror:example radius (r), calculate v, then: time (seconds) = (2*pi*r) / vrepeat until time = 86164 secondsworks out at approx 42 164 000 metres radius

How do you find out base of a given equation for example 25 by 3 equals 7 all the values are in base b you are required to find out the value of b How will you find it?
You can find out the base by the following way.. Let us consider the example: (25/3)=7 To find its base let as assume it has base r.. Now find the value of r by converting the nums in decimal: (2r+3)/3=7 (As 25 in base r is equal to 2*(r^1) + 5*(r^0) in decimal) 2r+3=21 2r=21-3 2r=18 r=9
