So multiply 5x6 to get 30
Then times 6x3 to get 18
Next times 4x9 to get 36
Add 30, 18, and 36 together to get
84
Answer:
254.4 in²
Step-by-step explanation:
Area of a circle is given by the formula:

Our radius is 9 so we substitute this into the equation:
π(9)² = 81π
81π = 254.4 in²
5(3x+7)=3(5x+7)
15x+35=15x+21
cancel out the 15x. If you bring over one of the 15x it's going to naturally cancel each other out.
35=21
35 does not equal 21
it would be the equal sign with the slash coming through it
What are the other ratios?
