Question

The diameter of a circle is 6 ft, what is its area?

Answer 1

28.27 ft

Explanation:

equation for the area of a circle: πr²

the radius (r) is the diameter ÷ 2, so it would be 6 ÷ 2 = 3

now, plug in the results into the given equation:

π3² = 28.27

this value is approximate

Answer 2

28.27 ft

Explanation:

Diameter = 6ft

Radius = 3ft

Area = π(r)²

= π(3)²

= π(9)

≈ 28.27 ft
