Answer:

d

Step-by-step explanation:

surface area of cylinder=2πr(r+h)

2*3.14*4(4+7)

25.12*11

276.3in²

Answer:

Step-by-step explanation:

2πrh+2πr^2 is the formula for finding the surface area of a cylinder.

Since the question said to use 3.14 for pi,

2 * 3.14 * 4* 7 + 2*3.14*16

= 175.84 + 100.48

= 276.32 in^2

So, the answer is d, 276.3 (rounded to 1 decimal place)
