Answer:
Step-by-step explanation: pi r^2
so 42/2 equals 21 radius
volume=22/7 x 21^2
v=1385
49.99 = 0.6x, where x = original coat of jacket.
To solve for x divide both sides by 0.6, and you get x = $83.32 (rounded)
Answer:

Step-by-step explanation:
Use the midpoint formula:

We want to find the midpoint of the line
that has endpoints.

We simplify to get;

This finally gives:

The correct answer is A.
7, you divide the 14 by 2 because the qr is two times the length of gh, therefore 7 is two times the length of fh
