Answer 1

Answer:

4cm + 4cm + 4cm

=12 cm

hope it helps

Answer 2

Explanation:

Diameter of this circle = (4 + 4 + 4) cm = 12 cm

Radius = Diameter/2

Radius of this circle = 12/2 cm = 6 cm

Perimeter of a circle is known as it's circumference.

The circumference of this circle = 2πr

where r means radius and π = 22/7 .

Circumference of this circle

= 2 × 22/7 × 6 cm

= (44 × 6) / 7 cm

= 264/7 cm

Answer:

The circumference of this circle is 37.7 cm (approx.)

Reason:

The reason I took the approximate value of it's circumference because 264/7 is an repeating and non-terminating number.
