Solution:

Given that,

We have to find the area of circle

The area of circle is given as:

$A = \pi r^2$

Where, "r" is the radius of circle

Figure 1

From figure,

Diameter = 14 m

$Radius = (diameter)/(2)\\\\Radius = (14)/(2)\\\\Radius = 7$

Thus,

$Area = 3.14 * 7^2\\\\Area = 153.86$

$Area \approx 153.9$

Thus area of circle is 153.9 square meter

Figure 2

Radius = 5 feet

Therefore,

$Area = 3.14 * 5^2\\\\Area = 78.5$

Thus area of circle is 78.5 square meter
