Answer»

here \: is \: your \: answer \\ area \: of \: circle \: = \pi \: {r}^{2} \\ now \\ \pi = \frac{22}{7} \: and \: radius \: = 42 \: cm \: \\ so \: area \: will \: be \\ = \pi \: {r }^{2} \\ = \frac{22}{7} \times 42 \times 42 \\ = 22 \times 6 \times 42 \\ = 5544 \: {cm}^{2} \\ now \: circumference \: of \: circe \: = 2\pi \: r \\ now \\ = 2 \times \frac{22}{7} \times 42 \\ = 2 \times 22 \times 6 \\ = 264 \: {cm }^{2} \\ hope \: it \: helped \: \\ plz \: mark \: as \: brianliest \\ \\ \\ \\ stay \: safe \: stay \: safe
