2*pi*R should be substituted in. 2*13*3 = 78
Step-by-step explanation:
II will be the 90° clockwise rotation,
III will be the translation
IV will be the 180° rotation
V will be the 90° counter clockwise rotation
So,
First, notice that all of the answer options are in completed square form. So all we have to do is complete the square for the initial equation and see which equation it matches.

Isolate the constant term.

Add the necessary amount to both sides (halve the x term and square it).

Factor the completed square.

This equation is identical to the equation in option B.
The correct answer is B.
Answer:
60
Step-by-step explanation:
6 times 2 equals 12
12 times 5 equal 60
Option B:
is the ratio used to convert to miles to feet.
Explanation:
Given that the distance is 1.7 miles
We need to convert the distance 1.7 miles to feet.
The ratio of miles to feet can be determined by finding how many feet are there in a mile.
There are 5280 feet in a mile.
To convert the miles to feet, we need to multiply the mile by 5280 feet.
Thus, the distance is given by

Hence, the distance of 1.7 miles to feet is 8976 feet.
Thus, the ratio that is required to convert miles to feet is 
Therefore, Option B is the correct answer.
