the side of the square is 16cm so the diameter of the circle is 16cm

The radius of the circle is 8cm since the radius is half the diameter

To A=πr^2 in which r=8

so A=πr^2=π·82≈201.06193

Answer : 200.96cm²

Known

Diameter = 16cm

Question

Area of the circle

Way to do

#Find the radius first to get the area

radius = diameter : 2

radius = 16cm : 2

radius = 8cm

#After that, find the area

Area = π × r²

Area = π × (8cm)²

Area = π × 64cm²

Area = 3.14 × 64cm²

Area = 200.96cm²

Note

π (phi) = 22/7 or 3.14

r = diameter : 2

Area of circle = π ×r²

Perimeter of the circle = π×d

r = radius

d = diameter

Btw pls make me the brainlest :(
