Ahollow sphere im which circus motor cyclist performs his stunts ha s a diameter of 7 metre . find the area available for motor cyclist for ridung

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 =

Radius =

Thus, the area  

(Taking the value of π =3.14)

So, the area = 154 metre²(approximately)

Therefore, the area available for motorcyclist for riding is 154 metre².
