14 m

Answer 1

138.16

Explanation:

Answer 2

153.86 sq m

Explanation:

Area if a circle is:

A = pi•r^2

You have diameter = 14, so the radius (the r in the formula) is HALF the diameter. The radius for your circle is 7.

Area = pi•7^2

The directions said to use 3.14 for pi and do not round.

A = 3.14•7^2

A = 3.14•49

A = 153.86m^2

The units are square meters.
