B at least 70% i had the same question before and that was correct
The value of a=7 will make the equation true
Answer:
Fr^2/Gm_2=m_1
Step-by-step explanation:
What you do first is you have to cross-multiply so f*r^2 and 1*gm_1m_2 to get
Fr^2=Gm_1m_2. Next you will divide Gm_2 from both sides to get
Fr^2/Gm_2=m_1 as your answer.
The area of a circle is given by the formula:
A =

r^2
Since

= 3.14, and r = 6, sub these values into the equation,
A = 3.14 x 6^2
= 113.04
Hope this helped!
