Question

find the curved surface area of cone do height is 12 centimetre and base radius is 50 cm​

Answer 1

Answer:

$8072.91  cm^2$

Step-by-step explanation:

Lateral surface area of a cone:

L = πrs = πr$\sqrt{r^2+h^2}$

L= $3.14*50*\sqrt{50^2+12^2}$

L= $3.14*50*\sqrt{2500+144} \\\\3.14*50*\sqrt{2644}\\ \\3.14*50*51.41\\\\=8072.91$
