Answer:

S = 2π(4)(16) + 2π(4²)

So option A is correct; S = 2 pi (4) squared + 2 pi (4) (16)

Step-by-step explanation:

The formula for total surface area of a cylinder is;

Total surface Area; S = 2πrh + 2πr²

Now,we are given;

Height;h =16 inches

Radius;r = 4 inches

Thus, plugging in the values into the Area formula, we have;

S = 2π(4)(16) + 2π(4²)

The correct answer from the options given is;

S = 2 pi (4) squared + 2 pi (4) (16)

A piece of wire 6 cm long weighs 30 grams. What is the weight of an 8 m length of the same wire?
Feliz [49]

Answer:

4000 gm

Step-by-step explanation:

We can use ratios to solve

Change 8 m to cm

8m * 100cm/1m = 800 cm

6 cm             800 cm

-------------  = ------------

30 grams      x gm

Using cross products

6 * x = 800 * 30

6x = 24000

Divide by 6

6x/6 = 24000/6

x = 4000 gm

Pamela and Debbie are shelving books at a public library. Pamela shelves 26 books at a time, whereas Debbie shelves 7 at a time.
Ira Lisetskai [31]

If both Pamela and Debbie can shelf the same number of books at the end, the smallest number of books each could have shelved is 182

The number of books that Pamela can shelf at a time = 26

The number of books that Debbie can shelf at a time = 7

If both Pamela and Debbie can shelf the same number of books at the end, the smallest number of books each could have shelved is the least common multiple of 26 and 7

The Least common multiple of 26 and 7  = 182

Therefore, if both Pamela and Debbie can shelf the same number of books at the end, the smallest number of books each could have shelved is 182
