Question

the diameter of the base and height of a cone are 12 m and 10 M find the total surface area of cone

Answer 1

Answer:

Step-by-step explanation:

Radius = 6m

Height = 10m

$l^{2} = \sqrt{r^{2} + h^{2} }$

l = $\sqrt{ 36 + 100}$

l = 11.661 m

TSA of cone = πr ( l + r )

TSA = 18. 8571 ( 17.661)

TSA = 333.0352431
