volume: volume of cone is 1/3πr^2h

radius is 2

height is 6

plug into equation: 1/3π(2)^2*6=about 2.55 or 8π

surface area: surface area of cone is πrs+πr^2 where s is slant height.

to find slant height use pythagorean theorem: √(2^2+6^2)=√40

radius: 2

height:6

slant height: √40

plug into equation: π(2)(√40)+π(2^2)=about 52.30 or 4√10π+4π
