Question

Find
circle having
approximate circumference of
having diameter = 12cm

Answer 1

Answer:

Diameter is 12 cm; (b) radius is 6 cm; and (c) area is 36π cm2.

Explanation:

If r is the radius of a circle, then its circumference is 2πr and area is πr2.

As circumference is given to be 12π, we have

2πr=12π

or r=12π2π=6 cm.

As such radius is 6 cm and diameter being double of radius, diameter is 2×6=12 cm.

and area is π×62=36π cm2.
