(C) 132 cm
(D) 154 cm​

Answer 1

Answer:

option A is the correct

Answer 2

Answer:(d) 154 cm sq is the correct answer

$circumference \: of \: the \: circle \: = 44cm \\ = > 2\pi \: r = 44cm \\ = > 2 \times \frac{22}{7} \times r = 44 \\ = > r = \frac{44 \times 7}{22 \times 2} = 7c m \\ \\ area \: of \: the \: circle \: = \pi \: {r}^{2} \\ = \frac{22}{7} \times 7 \times 7 \\ = 22 \times 7 \\ = 154 \: cm \: sq$
