Answer:
the area available for motorcyclist for riding is 154 metre².
Step-by-step explanation:
Given:
Diameter = 7 metre.
Now, to find the area available for motorcyclist for riding.
So, by putting the formula of area we solve it:
Radius = [tex]diameter\div 2[/tex]
Radius = [tex]7\div 2=3.5 metre[/tex]
Thus, the area [tex]=4\pi r^2[/tex]
(Taking the value of π =3.14)
[tex]=4\times 3.14\times 3.5^2[/tex]
[tex]=12.56\times 12.25[/tex]
[tex]=153.86[/tex]
So, the area = 154 metre²(approximately)
Therefore, the area available for motorcyclist for riding is 154 metre².
