Answer: A= 460 mm2
Step-by-step explanation:
Hi, since the circumference formula is :
C = 2 π r
Where r is the radius, we can solve the formula for the radius replacing with the value given:
76 =2 π r
76 / (2 π) = r
r = 12.1 mm
Now , we have to apply the formula for the area of a circle.
A = π r^2
A = π (12.1)^2
A= 459.96 mm2= 460 mm2 (rounded to the nearest tenth, since .9 is higher than .5)
Feel free to ask for more if needed or if you did not understand something.

Step-by-step explanation:
Thanks!
Recall your d = rt, distance = rate * time.
notice, the distance are the same, say it was "d" miles.
and if car A is travelling at a speed of say "r" mph, then B is going at "r+15" mph.
how far is B going? well, r + 15.
2y-2>-4+2. Add 2 to both sides. Now you have 2y>-2+2. Erm. I might be wrong since I JUST learned this unit and I made some mistakes. Ok soo, add 2 to both sides again. Now you have 2y+2>2. Subtract 2 from both sides. You now have 2y>0. You have no solution since 2 can't be divided by 0. I'm probably wrong but I hope I helped...ish.
