The lateral area of a cone would be: One half of circumference of the base multiplied by the slant height. Basically 1/2 [( Pi x D) x Slant height) Where "D" is the diameter of the base of the cone. (Pi x D) is the Circumference of the base Slant height  Length of a line from the base to the top of a prism, shape, etc.

yes. that is correct.

ayeitsdrewBest ResponseYou've already chosen the best response.0
so that would be 94.2 and then you take that times the slant height whjich is 28 right?

Okay, cones and pyramids are relatively different. The formula for this one would be SA=3.14rs+3.14r^2

ayeitsdrewBest ResponseYou've already chosen the best response.0
ok so 3.14 times the radius?

ayeitsdrewBest ResponseYou've already chosen the best response.0
wait no 3.14 x r x r
 one year ago

ayeitsdrewBest ResponseYou've already chosen the best response.0
and then do you add that to 3.14 x 4 x 4

ayeitsdrewBest ResponseYou've already chosen the best response.0
ok so the answer is 138.16
