Question

Can someone please help me I would appreciate it and if u can explain it that would be great to please help.

Answer 1

Use this equation: $A=2 \pi rh+2 \pi r^2$
Turning into: $A = 2 \pi (3)(5)+2 \pi (3)^2$


Radius (r) will be A = 3
Height (h) will be A = 5
T.S.A. (a) = TOTAL SURFACE AREA

We will get T.S.A. = 150.8571 round to 150.86
