1017.36 m^2
<u>Step-by-step explanation:</u>
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
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
x=3, y=4
hope this helps!
