Question

find the degree subtended at the centre of a circle by an arc whose length is 15cm, if the redius of the circle is 25cm.​

Answer 1

Step-by-step explanation:

theta=L/R

THETA=15/25

THETA=0.6

ttherefor 0.6rad=0.6*π/180

=34.36 degree

and 34°36'28"

Answer 2

Answer:

=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
