Step 1:
first let us convert the two decimals into fractions.
0.36=36/100 (since there are two digits after decimal point we divide by 100)
2.4=24/10 (since there are one digit after decimal point we divide by 10)
now we can multiply the fractions
×
multiplying numerator with numerator and denominator with denominator:

=
Now we can convert this back to decimal
864/1000=0.864, moving decimal three digits to the left since we have three zeros in the denominator that is 1000.
Answer=0.864
6 square units.
1 sq units would be 1 mile, so 4 units are 4 miles. A little bit more than 4 is 6.
Answer:
The third option has a linear slope.
Step-by-step explanation:
There is a similar shortcut for multiplying decimal numbers by numbers such as 10, 100, and 1000: Move the decimal point to the right as many places as there are zeros in the factor. Move the decimal point one step to the right (10 has one zero). Move the decimal point two steps to the right (100 has two zeros).
Since you are given the area, we can solve for radius with this equation:


The radius is 11, so the diameter must be 2 times that, which is 22. With the correct units, the answer is
22 units²
