Answer:
Explanation:
Volume of cone = ⅓ × pi radius² × height = ⅓ × pi r² × h
Height = 40, slant height = 41
We need to find the radius, so let's use Pythagoras Theorem to find ittt.
Using PT,
Radius² = 41² - 40² = 81
Radius = root 81 = 9
Now, let's replace.
Volume = ⅓ × pi × 9² × 40 = 1080 pi = 3392.92 = 3393
