Answer:
Area of semicircular lawn is 9.82 square meter.
Step-by-step explanation:
Given:
Diameter of the semicircle = 5 m
So we will find the radius.
Radius is half of the diameter.
Radius 
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 = 
Hence Area of semicircular lawn is 9.82 square meter.
Answer:
3600(seconds) can also be expressed as 1(kilometer/hour) = 5/18 (meters/second), which is its simplified form. To convert km/h to m/s, directly multiply the given value of speed by the fraction 5/18.
