Question

4. What is the area of a circle whose diameter is 2cm?​

Answer 1

Step-by-step explanation:

Given:

Diameter of circle=2cm

To find

Area of circle

Proof:

r=D/2

r=2/2

r=1cm

Area of circle=πr^2

=3.14×(1)^2

=3.14cm^2

Answer 2

Answer:

3.14cm²

Step-by-step explanation:

Diameter = 2cm

Radius = 2/2 = 1cm

Area of a circle = π r²

                         = 22/7 × 1

                         = 22/7

                         = 3.14cm²
