Surface area is the area you get from a shape's net.
A net is an unfolded 3rd shape.
To find the surface area you use the equation A = 2xπrh + 2πr²
The answer would be 659.73 cm²
Hope this helps have a wonderful day!
Answer:
Convergent; 81
Step-by-step explanation:
r = term2/term1 = 8/9
8/9 < 1 so convergent
Sum = 9/(1 - 8/9)
= 9/(1/9) = 81
Uhh
What is this??
