Question

Find the surface area of a cone with radius of 8.8 cm and slant height of 7.1 cm to the nearest square unit. Use 3.14 for pi.

Answer 1

SA = πr^2 + πrl
where l = slant height. Just plug the numbers into this formula.

Answer 2

can you explain less mathematically\
how you would explain to a beigginer

Answer 3

Ok. the formula I posted above is the formula for surface area for a cone. Just plug in numbers for the values they represent.
SA = πr^2 + πrl
SA = π(8.8)^2 + π(8.8)(7.1)
Just multiply and add.

Answer 4

thank you so much!
