The medicine capsule shown consists of a cylinder with a hemisphere at each end. the total length of the capsule is 18 millimeters. the diameter is 7 millimeters. which choice is the best approximation of the total surface area of the capsule? use 3.14 to approximate pi.

395.64 mm² . . . . . or . . . . . 3.9564 cm²

Step-by-step explanation:

The total surface area is that of a sphere of diameter 7 mm and the lateral area of a cylinder 11 mm long and 7 mm in diameter. An appropriate formula is ...

... A = 4π(d/2)² +πdh

... = πd(d +h)

... = 3.14×(7 mm)×(18 mm) = 395.64 mm²

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
