Question

Ken's landscape gardening business creates odd-shaped lawns that include semicircles. Find the area of this semicircular section of the lawn in this design. Usefor .

Answer 1

Area of semicircular lawn is 9.82 square meter.

Explanation:

Given:

Diameter of the semicircle = 5 m

So we will find the radius.

Radius is half of the diameter.

Radius
`r=(5)/(2)=2.5\ m`

We need to find the area of the lawn.

Solution:

Now we know that;

Area of semicircle is half times π times square of the radius.

framing in equation form we get;

Area of semicircular lawn =
`\frac12\pi r^2=\frac12*(22)/(7)* 2.5* 2.5=9.82\ m^2`

Hence Area of semicircular lawn is 9.82 square meter.
