Question

1. find the slant height of the cone. (with a diagram of a cone showing diameter 16 m and height 15 m)

Explanation:

Step1: Identify cone radius

Radius $r = \frac{16}{2} = 8$ m

Step2: Identify cone height

Height $h = 15$ m

Step3: Calculate slant height

Use Pythagoras: $l = \sqrt{r^2 + h^2} = \sqrt{8^2 + 15^2} = \sqrt{64 + 225} = \sqrt{289} = 17$ m

Answer:

17 m
