Question

7th-grade math pls help! (if you're going to help pls read the whole question)

Answer 1

Area of circle =πr²

= 22/7 × 4²

= 50.2 cm²

Area of square= 3²

= 9

Area of shaded region

= 50.2 - 9

= 41.2 cm²

i hope that this will surely help u mate .....

HAVE A GOOD DAY

Answer 2

Given

• Radius of circle = 4 cm
• Side of square = 3 cm

To Find :

• Area of shaded region

Solution :

$\bf Area_{region} = Area_{circle} - Area_{square} \\ \\ \bf Area_{region} = \pi {r}^{2} - {a}^{2} \\ \\ \tt \implies \frac{22}{7} \times {4}^{2} - {3}^{2} \\ \\ \tt \implies \frac{22}{7} \times 16 - 9 \\ \\ \tt \implies \frac{352}{7} - 9 \\ \\ \tt \implies \frac{352 - 63}{7} \\ \\ \tt \implies \frac{289}{7} \\ \\ \tt \implies41.28 \\ \\ \large \underline{\bf \green{ Area \: of \: shaded \: region \: is \: 41.28 \: {cm}^{2} }}$
