Question

What is the surface area of a cone with a radius of 6 centimeters and a slant height of 9 centimeters? Use 3.14 for pi .

282.6cm2

423.9cm2

452.16cm2

1,017.36cm2

Answer 1

Surface area=(3.14*radius*slant height)+(3.14*radius^2)

So your equation should be:
(3.14*6*9)+(3.14*6^2)

Then, 169.56+113.04 which equals 282.6 cm2
