Question 2
The height of a cone is 8 cm and the diameter of the base is 12 cm. find slant height
​

Answer 1

Step-by-step explanation:

Perimeter of the base (= 2π r) = 12 π cm

Therefore, radius r, of the base of the cone = 6 cm

Vertical height h of the cone = 8 cm

Slant height of the cone is the hypotenuse of a right triangle, whose two other sides are vertical height h of the cone, and radius r of the base. From Pythagoras theorem

r² + h² = (slant height)²; ==> 6² +8²= (slant height)²;

==> Slant height² = 36 + 64 = 100 cm²

Therefore,

Slant height = 10 cm.
