borishaifa [10]

Answer:

D. 59.66

Step-by-step explanation:

The formula is A = $\pi r^{2}[/tex\ Also the radius is half of the diameter. and [tex]\pi$ = 3.14

so we need to find the area's

9 x 9 = 81

81 x 3.14 = 254.34

Next circle.

10 x 10 = 100

100 x 3.14 = 314

Now to find the difference.

314 - 254.34 = 59.66

59.66

. The land area of Charlotte, NC is approximately 3 x 102 square miles.

lidiya [134]

Answer:

Option A

Step-by-step explanation:

Land area of Charlotte, NC = $3\times 10^2$ square miles

Scale to be used,

1 square miles = $6.4\times 10^2$ square acres

By this scale,

$3\times 10^2$ square miles = $(6.4\times 10^2)\times(3.2\times 10^2)$ square acres

= $(6.4\times 3)\times 10^{2+2}$

= $19.2\times 10^4$ square acres

= $1.92\times 10^5$ square acres

Therefore, Option A will be the correct option.
