Answer:

D) 4256\pi\:\text{cm}^2

Step-by-step explanation:

SA=2\pi r h+2\pi r^2\\\\SA=2\pi(28)(48)+2\pi(28)^2\\\\SA=2\pi(1344)+2\pi(784)\\\\SA=2688\pi+1568\pi\\\\SA=4256\pi\:\text{cm}^2

What's the question? The estimated product of two numbers that are not multiples of 10 is 2800.
Neporo4naja [7]

Seems to me like the question is:  What are the two numbers ?

They have to multiply to  2,800 . 
It's fairly easy to find two numbers that do that,  BUT ...
they're not supposed to be multiples of 10 .

1 x 2,800 = 2,800 . . . . . No good.  2,800 is a multiple of 10 .

2 x 1,400 = 2,800 . . . . . No good.  1,400 is a multiple of 10 .

4 x 700 = 2,800 . . . . . No good.  700 is a multiple of 10 .

5 x 560 = 2,800 . . . . . No good.  560 is a multiple of 10 .

7 x 400 = 2,800 . . . . . No good.  400 is a multiple of 10 .

8 x 350 = 2,800 . . . . . No good.  350 is a multiple of 10 .

10 x 280 = 2,800 . . . . . No good.  280 is a multiple of 10 .

14 x 200 = 2,800 . . . . . No good.  200 is a multiple of 10 .

16 x 175 = 2,800 . . . . . Finally !  Neither one is a multiple of 10 .

−1.64 as a mixed number in simplest form.
liraira [26]
Convert to a mixed number by placing the numbers to the right of the decimal over 100. Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.
