Find the surface area of the composite figure

791.7 in.²

Step-by-step explanation:

Surface area of the composite figure = ½(surface area of sphere) + surface area of cylinder

= ½(4πr²) + (2πr(h + r)

Where,

r = ½(12) = 6 in.

h = 9 in.

SA = ½(4*π*6²) + (2*π*6(9 + 6)

SA = ½(452.39) + 565.49

SA = 791.685

SA = 791.7 in.² (nearest tenth)

if this is really you s much. i only have 3 points left and i have 2 questions to ask

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
