Use a net to find the surface area of the cone to the nearest square centimeter. Use 3.14 for pi.

Given:

The radius of the base of the given cone = 5 cm

The slant height of the cone = 19 cm

To find the surface area of the given cone.

Formula

The surface area pf the given cone is,

where, r be the radius and

l be the slant height.

Now,

Taking, r = 5, l = 19 and π = 3.14 we get,

sq cm

or, sq cm

or, sq cm

Rounding off to the nearest square centimeter, we get;

Hence,

The surface area of the cone is 377 sq cm.

answer: a.   one is a factor of every whole number since every number is divisible by itself.
