R=square root of 10 is the answer
I have the same question why can’t I accept this comment HELPP
Answer:
C=15
Step-by-step explanation:
Equation: (7c-7)+(6c-8)=180
180 because a STRAIGHT LINE is 180degrees
Then you do 'math'
(7c+6c)-15=180
13c=195
c=15
Miles per hour is the conversion to use, the answer is 4 miles per hour if that is needed.
The area of the circle is pie times radius squared. In this case the radius is 3.5 and that to the second power would be 12.25
(What your finding is a half circle so you can divide by two if needed but the total area would not change since you would be adding them together anyway)
The rectangle is 77 because the area is base times height.
I hope I was helpful!
