If an angle has a measure of 90 degrees what percentage of t

If an angle has a measure of 90 degrees, what percentage of the entire circle\'s circumference does that angle subtend? To determine the percentage of a circle\'s circumference subtended by an angle with a measure off 90 degrees, compare the relative size of the angle measure in degrees to The length of the arc subtended by the angle. The measure of an angle in radians that opens an entire circle\'s circumference The measure of an angle in degrees that opens an entire circle\'s circumference The length of the circumference of the circle If an angle has a measure of Pi/2 radians, what percentage of the entire circle\'s circumference does that angle subtend? To determine the percentage of a circle\'s circumference subtended by an angle with a measure of pi/2 radians, compare the relative size of the angle measure in radians to The length of the circumference of the circle. The measure of an angle in degrees that opens an entire circle\'s circumference The length of the arc subtended by the angle. The measure of an angle in radians that opens an entire circle\'s circumference. Suppose an angle has a measure of 90 degrees. What is the measure of this angle in radians?

Solution

a) For 90 degree ======> %age of circumference = 25%

b) The measure of an angle in degrees that opens an entire circle\'s circumference.

c) For pi/2 radians ======> %age of circumference = 25%

d) The measure of an angle in radians that opens an entire circle\'s circumference.

e) 90 degree = 90*pi/180 = pi/2 radians
