Question

The lateral area of a cone is 500mc012-1.jpg cm2. The radius is 50 cm. Find the slant height to the nearest tenth.

10 cm
9.1 cm
14.2 cm
11.2 cm

Answer 1

\[500pi cm ^{2}\]

Answer 2

\[A_{l} = \Pi \times R \times S\]
where: Al - lateral area
R - radius
S - slant height
and \[S = \frac{ A_{l} }{ \Pi \times R } = \frac{ 500\Pi }{ \Pi \times 50 } = 10\]
