Please help me

I need correct asnwers

diameter = 12 cm

radius = 6cm

circumference = 12 cm ≈ 37.68 cm

area = 36 cm² ≈ 113.04 cm²

Step-by-step explanation:

r = radius

d = diameter

C = circumference

A = area

The diagram shows a circle with a diameter of 12 cm

Diameter

d = 12 cm

Radius

   r = d/2

⇒ r = 12/2

⇒ r = 6 cm

Circumference

   C = d

⇒ C = 12 cm

Area

A = r²

⇒ A = x 6²

⇒ A = 36 cm²

If you use = 3.14 then:

C = 37.68 cm

A = 113.04 cm²

Step-by-step explanation:

Radius:

r = d/2 (12/2) = 6cm

Diameter:

d = 2*r (6*2) = 12cm

Circumference of a circle:

C = 2*π*r (2*3.14*6) ≈ 37.7

Area of a circle:

A = π* (3.14*) = (3.14*36) ≈ 113.04

Hope this helps!
