Question

Area of circle whose radius is equal to the length of side of square with area 16 sqcm?
1️⃣ 16 cm
2️⃣ 16 sqcm
3️⃣ 16 sqcm
4️⃣ 16 cm​

Answer 1

Answer:

50.24 sqcm

Step-by-step explanation:

Area of square = 16 sqcm

Side of square = $\sqrt{16}$ = 4 cm          

Radius of circle = 4 cm

Therefore, area of circle = πr^2

                                        = 3.14 * 4 * 4

                                         = 50.24 sqcm

Answer 2

area of square = 16 sqcm

length of its side = Squareroot of 16

= 4

Area of a circle = pie(value is 22/7 or 3.14) × r^2

= 22/7 × 16

= 50.24
