Question

Find the area of each circle to the nearest tenth, if necessary. Use 3.14 for π.

​

Answer 1

The area of circle is 153.9 square meter

The area of circle is 78.5 square meter

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
