The lateral area of a cone is 400 pi cm^2. the radius is 10 cm. find the slant height to the nearest tenth.

ANSWER

The slant height is 40cm.

EXPLANATION

The lateral area of a cone is given by:

where r=10cm is the radius of the circle and l is the slant height.

It was also given that, the lateral area is 400π cm²

We substitute the values to get,

We now divide both sides by 10π.

This implies that,

Hence the slant height is 40cm.

the answer is two. hope this !

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
