Question

if an length of an arc is 44cm and the angle subtended by it at the centre of the circle is 315° then find the radius of the circle.​

Answer 1

ANSWER-)

"

Length=44cm

theta=315°

we have to convert this angle in degree to radian -)

=pie/180×315= 5.49 rad (rad is the symbol for radian or you can denote it with 'c' also)

now we know H= theta × radius

= 44/5.49

440/549 ×100 = 8.01 cm

hope it helps you ✌
