Surface Area (SA) of a Cylinder formula:
SA = 2*pi*r*h+2*pi*r^2
If you fill in the formula:
SA = 2*3.14*2*9+2*3.14*2^2
Simplify:
SA = 6.28*18+6.28*4
SA = 113.04 + 25.12
SA = 138.16 in
I hope I helped
If its wrong I'm super duper extra sorry!
Answer:
-15.3, -15.1, -12.3, -11.4, -11.4, 19.6
Step-by-step explanation:
Answer:
15, C
Step-by-step explanation:
Any number is equally likely to appear. Therefore, we have 3/20 * 100 = 15. This is C.
Hope this helped!

Using the Sine Rule:-
20 /sin 45 = BC / sin 30
BC = 20 sin 30 / sin45
= 20 * 1/2 / 1 / sqrt2
= 20 * 1/2 * sqrt2
= 10 sqrt2 answer
