Answer:

331

558

683

Explanation:

LA = 3.14x8.5x12.4 = 330.9 = 331

SA = 331+3.14x8.5^2 = 557.9 = 558

V = 1/3x3.14x(8.5^2)x(12.4^2-8.5^2)^0.5 = 682.7 = 683

Answer:

Explanation:

LA = pi*r*l = 3.14*8.5*12.4 = 331

SA = LA + pi*r^2 = 331 + 3.14*8.5^2 = 558

V = 1/3*pi*r^2*h = 1/3*3.14*(8.5^2)*sqrt(12.4^2-8.5^2) = 683
