major arc/(28π) = 240/360 = 2/3
major arc = 28π(2/3) = 56π/3
This becomes the circumference of the base of the cone
let the radius be r
2πr = 56π/3
r = 28/3
state your conclusion using the correct units
A sector of radius 14 cm subtend an angle of 240 degree at the center of the circle is bent to form a cone calculate the base radius of the cone
