Question

If radius of a circle is 42cm , Find its area and circumference?​

Answer 1

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

Answer 2

Step-by-step explanation:

• radius of a circle r =42cm
• area of circle =πrsquare
• =22÷7×42×42
• =22×42×6
• =5544sqcm
• circumference of circle =2πr
• =2×22/4×42
• =264cm
