Question

The radius of the base of a cone is 6 cm and its height is 8 cm find its covered surface area

Answer 1

Answer:

CSA of cone =3.14 x 6 x 10 = 188.4cm^2

Step-by-step explanation:

l= slant height

l = $\sqrt{base^2 + height^2}$

l = $\sqrt{6^2+8^2}$

l = $\sqrt{100}= 10$

CSA of cone = πrl = 3.14 x 6 x 10 = 188.4cm^2
