Answer:
<h2>The answer is 615 m²</h2>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius
From the question
r = 14 m
π = 3.14
The area of the circle is
A = 3.14 × ( 14 ) ²
= 3.14 × 196
= 615.44
We have the final answer as
<h3>615 m² to the nearest whole number</h3>
Hope this helps you
