The diagram shows a shape made from a solid cube and
a solid cylinder
The cube has sides of length
8.7 cm. The cylinder has a
radius of 2.7 cm and a height
of 4.9 cm
Calculate the total surface
area of the solid shape,
Give your answer correct to
3 significant figures,​

Step-by-step explanation:

Its easy split the figure in to 2 parts then add the individual area you will get the area of whole surface area,

first calculate area of cylinder using formula below,

area of cylinder = 2*pi*r*h+2*pi*r^2

now again find the area of cube using formula ,

area of cube = 6 (S^2)

now add these 2 you will get your answer

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
