1.	The slant height of a cone is 12cm. If the radius of the cone is 5cm, find the height of the cone.
Answer» Base = Radius = 5cm , slant height = hypotenuse =12cmHeight = perpendicular = ?By Pythagoras theoremH^2 = B^2 + P^212^2 = 5^2 + P^2144 = 25 + P^2144 - 25 = P^2119 = P^2√119 = P10•90 cm P r= 5 cm, l= 12 cm using formula , l= √r²+h² = h=√l² - r²=√12²-5² = 10.91cm
