Question

The tops of the sold rocket boosters used to launch the space shuttle are cones of diameter 3.7 m and slant height 5.4 m. Find the angle that the curved surface of the cone makes with a diameter, to the nearest tenth of a degree.

Answer 1

70 degree

Answer 2

diameter=3.7 => radius=1.85
let x be the measure of the angle
cosx=1.85/5.4
=> x=70
