Question

Find the angle in degrees of standard at the centre of a circle by an Arc whose length is 15 CM if the radius of the circle is 25cm

Answer 1

Answer:

the degree measures of the angle subtended at the centre of the circle is 34'36

Step-by-step explanation:

l=15cms

r=25cms

θ=l/r

=15/25

3/5=0.6 radians

wkt 1 radian =180/π

0.6 radians=0.6*180/π

=(0.6*180*7)/22=34.36

Thus the degree measures of the angle subtended at the centre of the circle is 34'36
