Question

the lateral area of a cone is 555 pi cm ^2. the radius is 15.1 cm. What is the slant height to the nearest tenth of a centimeter

Answer 1

A. 36.8 cm........

GOOD LUCK!

Answer 2

The lateral area of a circular cone of slant height
`l` and radius
`r` is

`LSA=\pi r l`.

Here
`LSA=555 \pi` and
`r=15.1\;cm`.

Using the formula of the surface area,

`image`.

The slant height of the cone is
`36.8\;cm`.
