Question

What is the total surface area of a right circular cone of height 14 cm and base radius 7 cm? Select one:

Answer 1

l=
$\sqrt{{h}^{2} + {r}^{2} }$
l=
$\sqrt{ {14}^{2} + {7}^{2} }$
l=
$\sqrt{196 + 49}$

total surface area of cone=μrl+μr²
= 498.3cm²

Answer 2

TSA=497 .90 is your answer I think so
