Question

I'll mark the best or the first as brainliest.

Answer 1

Answer:

Here the error is

$\pi {r}^{2}$

It should have been ,

$2\pi {r}^{2}$

Step-by-step explanation:

Corrected formula:

$2\pi {r}^{2} + 2\pi rh$

$= 2\pi ({5}^{2}) + 2\pi(5)(10.6)$

$= 50\pi + 106\pi$

$= 156\pi$

$= 489.84 {yd}^{2}$

$approx . \: 489.8 {yd}^{2} (ans)$
