Question

The seventh-grade class is building target areas for a PE activity. The bases for the game will be in a circular shape. The diameter of each circle is 6 feet. Approximately how many square feet of the turf need to be painted for a base circle? Use 3.14 for π and round your answer to the nearest tenth

Answer 1

I think the answer is 28.3. You would take 3.14 and multiply it by 3^2.

Answer 2

By definition, the area of a circle is given by:
 $A = \pi * r ^ 2$
 Where,
 r: radius of the circle.
 Substituting the values in the given expression, we have:
 $A = 3.14 * (3) ^ 2 A = 28.26 feet ^ 2$
 Rounding to the nearest tenth we have:
 $A=28.3feet^2$
 Answer:
 Approximately needed:
 $A=28.3feet^2$
