Answer:
[tex]2\pi \: rh + 2\pi {r}^{2} = 2(t \times {r}^{2} )[/tex]
Step-by-step explanation:
The TSA of the cylinder
[tex]2\pi \: rh + 2\pi {r}^{2} [/tex]
In Mathematics, 'is' is =
Twice means 2( )
Product means ×
So we have
[tex]2\pi \: rh + 2\pi {r}^{2} = 2(t \times {r}^{2} )[/tex]
as the answer.
