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

28.3 Square Feet

Explanation:

Diameter of circle=6 feet

then

radius=diameter/2

=6/2

=3 feet

The area of circle is given by

A = πr^2

where r is the radius of the circle

Putting the values of pi and r

A =(3.14)(3)^2

=3.14*9

=28.26 sq. feet

Rounding off to the nearest tenth

A=28.3 sq. feet

So, 28.3 sq. feet need to be painted for the base circle ..
