Question

what will be the answer? 2x+9x = π r2​

Answer 1

Answer:

$x = \frac{2 {r}^{2} }{7}$

Step-by-step explanation:

$2x + 9x = \pi {r}^{2} \\ \\ \implies \: 11x = \pi {r}^{2} \\ \\ \implies \: 11x = \frac{22}{7} {r}^{2} \\ \\ \implies \: x = \frac{22 {r}^{2} }{7 \times 11} \\ \\ \implies \: x = \frac{ \cancel{22 }{r}^{2} }{7 \times \cancel{11} } \\ \\ \implies \: x = \frac{2 {r}^{2} }{7}$
