Answer:
A) 145.3 cm^2
Step-by-step explanation:
The formula for the area of a circle is A = π r^2
So to find the area we would plug the radius of 6.8 into the formula
Area = π (6.8)^2
Area = (3.14) (6.8)^2
Area = 145.27
Area = 145.3
I tried every combination. there seems to be something wrong with the informations you gave.
the second equation contains errors, and none of these 4 points can be solutions to the first equation alone
