help please with my work

so on the top it says 6 inches. that is your diameter. divide the diameter by 2 to get "r" your radius. so 6/2=3. r=3. your height (h) is 8. you know everything you need to know, so now you plug in the radius and height to the equation. it'll look like this: 2(3.14)(3)^2+2(3.14)(3)(8). it equals 207.24
