Answer 1

Answer:

total surface area=332.5cm^2

Step-by-step explanation:

given diameter =7cm

radius=7/2=3.5

total surface area of solid =surface area of cubical part + CSA of hemispherical part -area of base of hemispherical part

=6(edge)^2+2πr^2-πr^2

=6(edge)^2+πr^2

=6(7)^2+22/7×(3.5)^2

=294+38.5

=332.5cm^2

therefore,total surface area of solid =332.5cm^2
