cone is formed by bending a sector of a circle having an angle of 288 degrees.find the radius of the base of the cone if the diameter of the circle is 18cm

Answer 1

Ii=9*288=2592
2592/360=7.2cm

Answer 2

9*288 =2592
2592 /360 =7.cm

Answer 3

pi D = 18 pi
so circumference of base circle = (288/360) *18 pi
radius = circumference / 2 pi
= 9 (288/360) = 7.20 cm
