The surface area of a cylinder is the area of the bases plus the area of the side, or SA = 2*A₁ + A₂
Since the area of a circle is
,
SA = 2*(
) + A₂
Since the area of the side is height * the circumference of the circle or A₂ = h *
, then SA must be;
SA =
SA =
SA =

Answer:the total cost of the collar is $5.11
Step-by-step explanation:
To make a collar for her dog, she needs to buy some chain,a clasp, and a name tag.
The length of the chain that she wants to buy is 40 centimeters.
1000 centimeters = 1 meter
40 centimeters = 40/1000 = 0.04 meters.
One meter of chain costs $9.75. Therefore, 0.04 meters of chain would cost
0.04 × 9.75 = $0.39
The clasp is $1.29 and the name tag is $3.43. Therefore, the total cost of the collar would be
0.39 + 1.29 + 3.43 = $5.11
