The linear speed of a body revolving at 1200 RPM in a circular path of 0.8 meter radius would be closed to?

Circumference of the path = pi times the diameter = 2 pi times the radius = 1.6 pi.
1200 rpm = 1200 circumferences per minute = (1,200 x 1.6 pi) = 1,920 pi inches/min
= 6,031.9 inches/minute (rounded)
= 502.7 feet/minute (rounded)
= 5.71 miles/hour (rounded)

How do you determine the circular area of a lawn?
pi radius squared. (radius squared, then multiply by pi.)
What is the measurement of base?
The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.
What is the differences between curvilinear motion and circular motion?
Curve linear is antonym to linear. Circular is one among many curvelinear motions. In case of circular there will be a constant radius but in curvelinear radius would change at every instant
How does a change in radius effect linear velocity?
For circular motion, linear speed = angular speed (in radians) x radius. How the radius affects speed depends what assumptions you make about the problem. For example, if you assume the radius increases but the angular speed does not, then of course the linear speed will increase.
What will be the velocity of a satellite which is revolving around the earth in a circular orbit the radius R if the radius is increased from R to RR what will be the velocity?
the velocity will be velocity divided by square root of 2

What is the radius of a cylinder?
The radius of a cylinder is half the thickness of its circular cross section.
How do you convert angular speed to linear speed?
divide the linear speed by the radius
How do you convert rpm into meter per seond?
rpm is a large (while radian/second is a small) scale unit of circular displacement (rotation) while meter/second is that of linear displacement.according to the relationv=rw wherev = linear velocity (in m/s)w (omega) = angular velocity / circular velocity in (rpm or rad/sec)r = radius of the circle in which body is rotating.we can assume that rpm times radius becomes equal to meter per second.Badeekh Akbar

What is geometric mean radius?
The radius is the distance between the centre of a circular arc and a point on the arc.
What is the radius of England?
Radius is a sensible measure to use with a circular (or spherical) shape. England is neither.
