Answer:

Mallory flew in total 10,000 miles, rounded :D

Step-by-step explanation:

Since we're using rounding to place values, first we have to have the total amount of miles flown by Mallory, so we make the sum:

3,720 + 5,985 = 9,705 miles

then, we have to round thefirst digit to the right following this rule

0-4 is rounded down

5-9 is rounded up

now, since the number we want to round is the first digit on the left (9), and following the rules above, we change the "9" for a "10". the rest of the numbers are now transformed into zeros (0)

9,705 >>> rounding it up >>> 10,000

Answer:

option D . 254.34cm^2

Step-by-step explanation:

The picture of the question in the attached figure

The options are:

A . 56.52cm^2

B . 141.30cm^2

C . 1,017.36cm^2

D . 254.34cm^2

step 1

Find the diameter of the largest circle

we know that

The diameter of the largest circle is equal to the sum of the diameter of the two inside circles

$D=6+12=18\ cm$

step 2

Find the area of the largest circle

we know that

The area of the circle is given by the formula

$A=\pi r^2$

we have

$r=18/2=9\ cm$ ----> the radius is half the diameter

assume

$\pi=3.14$

substitute

$A=(3.14)(9^2)=254.34\ cm^2$

Two rectangles are similar. The ratio of their corresponding sides is 1:4.

larisa [96]

ratio of perimeter is the same as ratio of sides so perimeter would be 1:4

since area is in square units you need to square the ratio (1:4)^2 which is 1:16
