Question

I think it’s A am I right

Answer 1

Pi(r)(r)(2) + pi(diameter)(height)

3.14(4)(4)(2)+ 3.14(8)(1.5)

138.16

Answer 2

$\bf \textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\ ------\\ r=\stackrel{mm}{4}\\ h=\stackrel{cm}{1.5}\\ ~~~~\stackrel{mm}{15} \end{cases}\implies SA=2\pi (4)(15+4) \\\\\\ SA=8\pi (19)\implies SA=152\pi$
