Question

the circumference of circle is 3.14cm.find the radius and area of the circle (take π = 3.14​

Answer 1

Answer:

Step-by-step explanation:

The circumference of the circle = 3.14 cm ⇒ 2π r = 3.14 ⇒   2 x 3.14 x r = 3.14 ⇒r =3.14/(2 x 3.14)  = 0.5 cm

Then area of the circle = π r^2 = 3.14 x 0.5 x 0.5 = 0.785 cm^2

Answer 2

Answer:

Area: 0.785m² Radius = 1/2cm

Step-by-step explanation:

C=2pi r

3.14=2×3.14×r

3.14/6.28=r

r=1/2

Area=pi r²

3.14×1/2×1/2

3.14×1/4

0.785m²
