Answer:

1017.36m

Step-by-step explanation:

The formular for finding the total surface area of a sphere is 4πr²

Where π is 3.14 and from the question r is 9m

4X3.14X9²

4X3.14X81

1017.36m

1017.36 m^2

Step-by-step explanation:

Step 1:

Total Surface Area of sphere is given by

TSF= 4× π ×r²

Where r= radius of sphere

            π = 3.14

Step 2:

TSF = 4 × π × 9²        r=9m

     = 1017.36 m²
