Answer:
c. 198π units²
Step-by-step explanation:
We have to find the surface area of a cylinder.
We know that surface area of a cylinder= 2πrh+2πr²
where r is the radius
and h is the height of the cylinder.
here h=2 units and r=9 units
Surface area= 2π×9×2+2π×9×9
= 198π units²
Hence, correct option is:
c. 198π units²
I think the answer is c 19
Answer:
Simplify: -9.8n + 8.5
Step-by-step explanation:
2.5 - 5.8m - 4n + 6
(-5.8n - 4n = -9.8n)
( 2.5 + 6 = 8.5)
-9.8n + 8.5
