Answer 6

is there a number for how long the rectangle is?

Answer 7

hint:
the length of base of the rectangle, is:
\(L=2 \cdot 3.14 \cdot 7=...?\)
so the area of such rectangle, which represents the lateral surface, is:
\(S_L=H \cdot L=11 \cdot L=...?\)
now the area of each circle, is:
\(S_C=3.14\cdot 7^2=...?\)
so the area of the base surface, is:
\(A= 2\cdot S_C=...?\)
finally, the requested total surface, is:
\(S_T=S_L+A=S_L+2 \cdot S_C=...?\)
